9 Best Homework Help Websites

July 22, 2023

When I was in high school, resources for extra homework help weren’t exactly abundant. If you were struggling with a Shakespeare sonnet, you could always run to the bookstore and pick up a CliffNotes guide. SparkNotes was also gaining in popularity. But these early homework help resources had limited catalogs and were focused primarily on literature. Today, I imagine students suffer from the opposite problem—having too many choices when it comes to homework help websites. When the options are seemingly endless, knowing what to look out for takes on an added importance. Below, I’ll go through a list of 9 stand-out homework help websites and briefly discuss what makes them worth a visit.

Homework Help Websites – The Basics

The best homework help websites do more than just spit out an answer to that tricky math problem. They actually help students learn the material. Common features of homework help websites are educational videos and lectures, practice tests and quizzes, study tools like flashcards, and Q&As with experts. Many sites offer features that allow students to ask specific questions and get real-time feedback. There are also a number of services that offer one-on-one tutoring. Some homework help sites are free, while others require a paid subscription.

1) Khan Academy

Khan Academy is an amazing resource for students of all ages. It’s free, and it really is an academy—it offers full courses in a wide array of subjects, from pre-K math to high school physics. The courses consist of readings, video lectures, practice exercises, and quizzes. The breadth of material is impressive. In math alone, I see course listings for Algebra 1 and 2, Geometry, Trigonometry, Precalculus, Statistics, Multivariable calculus—you get the idea. Khan Academy also offers a wide variety of AP courses, state-specific curricula, test-prep programs, and life skill courses, like personal finance.

It’s important to note that Khan Academy isn’t a one-on-one tutoring platform. But because of their extensive library of material, the search function is especially powerful. Try it out. I did a search for argumentative essay help, and found a comprehensive guide to writing argumentative essays that was a part of a larger writing course.

Chegg is a paid homework help service. Unlike Khan Academy, Chegg isn’t built around specific courses. Rather, it offers a variety of homework-support resources. Among those resources are plagiarism and grammar checkers, a proofreading service, and a “math solver”, which allows students to enter a problem and get back both a solution and a detailed step-by-step explanation of how the problem was solved. Perhaps the most powerful tool Chegg offers is its “Expert Q&A” feature. This service allows students to take a picture of their homework problem, upload it to the site, and get a detailed response in return. Chegg’s emphasis on process and explanation make it a valuable educational resource for students—not just a way to get a quick answer.

Best Homework Help Websites (Continued)

Quizlet is a well-known and worthwhile study resource. It offers a variety of courses, and it also has an expert-response feature. But Quizlet’s best feature, in my option, is the flashcards tool. Students can create their own digital decks of cards and practice them on Quizlet—just like an old fashion set of index cards. I had a ton of success using Quizlet’s flash card feature to help me memorize words for my foreign language requirement in college. It’s a simple but powerful tool. Although often maligned as a learning method, rote rehearsal and spaced repetition are effective ways to encode information . Quizlet’s flashcard feature is a great way to put those techniques into practice.

4) Socratic

is an AI-powered homework support app that allows students to type or take pictures of questions and receive solutions right away. Since it works with AI, it relies on the web’s vast stores of accumulated knowledge—you’re not interacting with a human tutor. Nonetheless, I found it to be an extremely helpful tool. I tried it out first using a specific math problem. In just a few seconds I was provided with the solution and an explainer with relevant formulas, plus a graphic to help visualize the underlying logic. There were also suggested links to additional resources. For example, when I asked Socratic to explain how the German genitive case works, it suggested a YouTube video and a number of articles from blogs and other language-learning sites.

Since Socratic doesn’t feature courses or one-on-one tutoring support, I wouldn’t lean on it if I were really struggling in a particular class. But as a tool to check your work, make sure you’re on the right track, and become aware of additional resources, it’s worth a download.

5) Photomath

Photomath is, as you might have guessed, a site for math homework help. Like other homework help websites, Photomath allows students to take a picture of a problem and receive an instant, step-by-step solution. Included along with the solution is an explanation of relevant concepts and formulas, plus videos covering mathematical concepts. Photomath does offer a few basic courses, too. So if in addition to homework-specific help you want to brush up on the basics, they’ve got you covered in arithmetic, algebra, and calculus crash courses.

6) Studypool

Studypool is a paid homework support service that provides solutions to specific questions. Studypool offers support in all the major subjects, with a particular emphasis on science. Students can ask questions on everything from anatomy to physics. Like other services, students upload their exact questions or problems directly to the site. But Studypool’s payment model is a bit different: instead of paying for tutoring time or a monthly subscription, students pay for solutions to each question they submit. When a student submits a question, tutors submit bids to answer them. The student then can select which tutor/price option works best. After students select the price and tutor they want, they’re connected with the tutor and given the solution and explanation via messenger.

The draw of Studypool is that it gives students access to real (i.e., human) tutors who are experts in their field. The downside is that pricing isn’t transparent, and students pay per question.

7) College Info Geek

College Info Geek is the study-support website that I wish I knew about when I was in high school and college (they didn’t pay me to write that, I swear). The site focuses not on specific courses or questions, but on how to become a more effective learner. Here it’s all about “learning how to learn”—study tips, memorization and note-taking techniques, and much more. The articles are well-researched, clearly-communicated, practical, and comprehensive. For example, the article on how to improve your memory includes a breakdown of the different types of memory processes, memorization techniques, and even a discussion of how nutrition affects memory. College Info Geek is a great resource for everyone, not just high school and college students.

8) SparkNotes

Yes, Sparknotes made the list! The site offers lessons in a whole bunch of subjects—biology, chemistry, computer science, history, philosophy, math—but its specialty is literature. SparkNotes provides summaries and analyses of novels, short stories, poetry, and non-fiction, from The Canterbury Tales to Toni Morrison, Saul Bellow, and Junot Diaz. SparkNotes breaks down books into sub-sections and provides synopses and analyses for each section. There are also separate pages for character breakdowns, discussions of themes and motifs, and explanations of important quotes. I’d caution against using SparkNotes if you’re trying to “hack” a novel or poem and get simple answers about what it “means.” But as a way to supplement your own understanding and interpretation, it’s a great resource. Shmoop is also worth checking out for extra support in literature, poetry, mythology, and the history of literary movements.

9) Grammarly

I’m not sure if Grammarly is an obvious or unexpected choice to round out the list. Either way, it deserves a mention here. Grammarly is a writing tool. It checks and suggests corrections for incorrectly spelled words and misused punctuation. But Grammarly also scans and corrects for things like clarity and vocab usage. It flags sentences that are vague, or overly wordy, and alerts you if you’re using that flashy vocab word incorrectly. It even gives suggestions if it thinks your writing is a bit bland. I don’t see Grammarly as a crutch, but rather as a tool. It can help you master those pesky recurring grammar and usage issues. Always mix up effect and affect? Grammarly will continue to course correct until you’ve got it down yourself.

Homework Help Websites – Final Thoughts

None of the above homework help websites should be seen as a panacea. Each has benefits and drawbacks, strengths and weak points. The list is far from exhaustive. And the sites don’t have to be used in isolation. Try a few out, mix and match. College Info Geek is an excellent supplement to any study regimen. Socratic can be used as a tool to check answers for math homework, and at the same time you can use Grammarly to describe your problem to a tutor on Chegg. At their best, these sites are more than quick fixes to stubborn homework problems—they’re aids to genuine learning.

10 Best Homework Help Websites for Students

By Med Kharbach, PhD | Last Update: May 11, 2024

In the age of information, the pursuit of knowledge isn’t limited to the boundaries of a physical classroom. The internet, a vast repository of knowledge, provides an invaluable resource for students in need of assistance with their homework. But with such an expansive digital landscape, finding reliable, high-quality educational resources can often feel like searching for a needle in a haystack.

That’s where our curated list of the best homework help websites comes into play. To help you navigate the limitless sea of educational platforms, we’ve done the legwork and compiled a selection of the very best websites offering homework help. These websites, vetted for their quality and effectiveness, cover a broad range of subjects, ensuring that every student finds the assistance they need.

Homework Help Websites for Students

From math and science to language learning, social studies, and history, these platforms provide comprehensive resources that empower students to tackle their homework with confidence. Read on to explore our top picks and elevate your learning journey

1. AI Chatbots

Since I published this list on homework assistants, several shifts have occurred in the online landscape, one of which is the remarkable advancement of AI chatbots such as ChatGPT, Gemini, Copilot, Jasper, Perplexity AI, among others. It struck me that these tools, if harnessed with care and responsibility, could serve as invaluable allies in the homework help arena.

These AI companions can offer instant assistance with a wide range of subjects, from math to literature, making them a flexible resource for students seeking to deepen their understanding or overcome specific challenges. Moreover, their ability to provide tailored support and explanations can make the learning process more engaging and personalized. It’s crucial, though, for students to remain critical thinkers and not rely solely on these tools, using them to supplement their learning journey rather than replace traditional study methods and the invaluable guidance of teachers.

Brainly is a website that offers homework help with subjects such as Math, Social Studies, World Languages, Computer Science, Arts, Geography, Physics, Chemistry, Biology, History, among others. Homework help in Brainly is community-driven and is provided by other students, tutors, Phds, and teachers. There is also the option for students to work 1:1 with tutors live.

Teachers can also access materials to help them with the teaching of classic literature including lesson plans and several other customizable materials. Sparknotes offers the first month for free then you need to upgrade to access the site’s materials.

10- Khan Academy

Khan Academy is another very good platform students can use to access a plethora of educational resources covering different subject areas. The site offers tutorials, instructional videos, explainers, guides, lesson plans and many more.

Final thoughts

The landscape of education has been significantly altered by technology, and homework websites are no exception. They offer a range of features—from collaboration tools and assignment trackers to full-fledged courses—that are changing the way students engage with their studies. Whether it’s Khan Academy’s mastery learning approach or Chegg’s expert guidance, each platform brings its unique offerings to the table.

That being said, no homework website can replace the tactile experience of a teacher’s guidance, and not all are made equal. As with anything in the educational tech world, it’s crucial to critically evaluate the sources we rely on. In my experience, while some websites can indeed be lifesavers during crunch time or as complementary study aids, others can be more of a distraction than a help.

The best free homework help websites for students

Most people assume they need to pay for a tutor to get the best homework help.

But getting a tutor can cost a fair amount, especially if you’re an international student. 

Tutors in the US charge between US$25 to US$80 per hour teaching standard K-12 subjects like Math, English and Science.

Tutoring centres can charge between US$100 to US$200 per month for weekly sessions. 

Of course, these rates vary according to the subject. For example, tutoring rates for SAT and test prep can range between US$45 to US$100 per hour, according to Tutors.com .

The more advanced the subject, the more expensive the tutors are

If you’re a student on a budget, hiring a private tutor isn’t the most practical solution. But that doesn’t mean you can’t study well on your own.

All it takes is determination and knowing where to look for free online resources.

If you’re looking for the best homework help that won’t cost you a single cent, bookmark these lifesaving websites now:

Another highly recommended site for the best homework help online is Quizlet . It’s so popular that every two in three students in the US use it to help them learn better outside classes. 

Quizlet hosts solutions in over 60 subjects ranging from philosophy, sociology, algebra, computer science and languages.  There are in-depth explanations that use step-by-step explanations to show students how to solve complex problems. 

One of their greatest features is The Flashcards tool which helps students prepare for their assignments and quizzes.  Students can create their own interactive flashcards and study sets or use pre-made ones shared by other students and learners.

Homework websites for students.

Let’s dive right into some of the different types of websites, including homework help websites for college students, as well as students of all other levels.

1. Top Homework Helper

This site provides students with access to over 3,000 tutors who are available to help solve homework problems across an array of subjects, including: Science, Geometry, Accounting, History, Finance, Physics, Chemistry, College Homework, and more.

The site even offers help with test prep for the SAT , ACT, MCAT, GMAT and other college-level entrance exams.

3. Study Geek

Oftentimes, it is math that challenges most students. For this reason, Study Geek offers help solely in all levels of math. From Trigonometry to Calculus, Statistics to Algebra and more, this site leverages those who have earned their PhD in Mathematics to assist students.

A note of caution.

When seeking help online for homework or writing assignments, you may be tempted to let someone else do the work for you. However, that is considered cheating and/or plagiarism, and it results in serious consequences, such as being expelled.

Even when you feel like you cannot gather the strength to write a paper or complete an assignment, or you are worried you will fail, you must not give up. Instead, you can leverage resources like online tutors, family and friends, mentors, peers , professors, and teacher’s assistants.

It’s always in your own best interest to try to complete your own assignments. After all, that’s why you’re getting an education!

Some Extra Study Tips

Along with homework comes the need to study for exams. Homework acts as supplementary work to reiterate all the material you learn in your classes and prepare you on a consistent basis for an upcoming exam, as well as to retain the information.

Here are a few study tips that are useful for students of all ages and academic levels.

1. Note-Taking 101

Note-taking is more of an art than a science. When you are in class, whether it be online or in person, it’s important to take notes. But you don’t want to write everything down, so be aware of key topics and bold headlines, as well as lists. Take the main idea from each lesson and write it down in your own words.

Another useful tip for note-taking is to use different colors. You can use colors to either highlight or write, and this can be done strategically so that, for example, all dates are in red, all vocabulary words are in blue, etc. It’s an easy way for your mind to recognize and categorize different tidbits of information for better recall.

2. Read Out Loud

There are different types of learners — some are visual, others are auditory, for example. If you find yourself to be an auditory learner, which means you remember best when you hear something, then try reading to yourself out loud.

Another good time to read out loud is when you write a paper or complete homework that is a writing assignment. Oftentimes, our brain can see a typo and skip over it, but when you read it out loud, you are more likely to hear the mistake and be able to make the correction.

3. Time Management

Time management is an essential part of life, especially when you are a student. Be sure to write down homework deadlines and test dates so you can prepare in advance. Another benefit to writing down your deadlines and test dates in a planner is so that you won’t forget them.

When you have your assignments listed, it’s also easier to ask for help and manage your time. If you need help in a specific subject, you can reference one of the resources above and get in contact with a tutor or further study the subject matter before the assignment is due or the test date arrives.

The Bottom Line

Homework is not meant to be scary, and it doesn’t exist to waste your time or stress you out. Instead, it is there to better prepare you to retain course information so you can continue to build on what you already know.

However, it’s normal to need homework help, and while some people may use their family or friends for help, others need more in-depth assistance. Around-the-clock online homework help solutions are there for your every need. A wide variety exists so that no matter what level you are at and what subject you need help with, you will be able to find a subject matter expert that is there for you!

Understanding Assignments

What this handout is about.

The first step in any successful college writing venture is reading the assignment. While this sounds like a simple task, it can be a tough one. This handout will help you unravel your assignment and begin to craft an effective response. Much of the following advice will involve translating typical assignment terms and practices into meaningful clues to the type of writing your instructor expects. See our short video for more tips.

Basic beginnings

Regardless of the assignment, department, or instructor, adopting these two habits will serve you well :

• Read the assignment carefully as soon as you receive it. Do not put this task off—reading the assignment at the beginning will save you time, stress, and problems later. An assignment can look pretty straightforward at first, particularly if the instructor has provided lots of information. That does not mean it will not take time and effort to complete; you may even have to learn a new skill to complete the assignment.
• Ask the instructor about anything you do not understand. Do not hesitate to approach your instructor. Instructors would prefer to set you straight before you hand the paper in. That’s also when you will find their feedback most useful.

Assignment formats

Many assignments follow a basic format. Assignments often begin with an overview of the topic, include a central verb or verbs that describe the task, and offer some additional suggestions, questions, or prompts to get you started.

An Overview of Some Kind

The instructor might set the stage with some general discussion of the subject of the assignment, introduce the topic, or remind you of something pertinent that you have discussed in class. For example:

“Throughout history, gerbils have played a key role in politics,” or “In the last few weeks of class, we have focused on the evening wear of the housefly …”

The Task of the Assignment

Pay attention; this part tells you what to do when you write the paper. Look for the key verb or verbs in the sentence. Words like analyze, summarize, or compare direct you to think about your topic in a certain way. Also pay attention to words such as how, what, when, where, and why; these words guide your attention toward specific information. (See the section in this handout titled “Key Terms” for more information.)

“Analyze the effect that gerbils had on the Russian Revolution”, or “Suggest an interpretation of housefly undergarments that differs from Darwin’s.”

Additional Material to Think about

Here you will find some questions to use as springboards as you begin to think about the topic. Instructors usually include these questions as suggestions rather than requirements. Do not feel compelled to answer every question unless the instructor asks you to do so. Pay attention to the order of the questions. Sometimes they suggest the thinking process your instructor imagines you will need to follow to begin thinking about the topic.

“You may wish to consider the differing views held by Communist gerbils vs. Monarchist gerbils, or Can there be such a thing as ‘the housefly garment industry’ or is it just a home-based craft?”

These are the instructor’s comments about writing expectations:

“Be concise”, “Write effectively”, or “Argue furiously.”

Technical Details

These instructions usually indicate format rules or guidelines.

“Your paper must be typed in Palatino font on gray paper and must not exceed 600 pages. It is due on the anniversary of Mao Tse-tung’s death.”

The assignment’s parts may not appear in exactly this order, and each part may be very long or really short. Nonetheless, being aware of this standard pattern can help you understand what your instructor wants you to do.

Interpreting the assignment

Ask yourself a few basic questions as you read and jot down the answers on the assignment sheet:

Why did your instructor ask you to do this particular task?

Who is your audience.

• What kind of evidence do you need to support your ideas?

What kind of writing style is acceptable?

• What are the absolute rules of the paper?

Try to look at the question from the point of view of the instructor. Recognize that your instructor has a reason for giving you this assignment and for giving it to you at a particular point in the semester. In every assignment, the instructor has a challenge for you. This challenge could be anything from demonstrating an ability to think clearly to demonstrating an ability to use the library. See the assignment not as a vague suggestion of what to do but as an opportunity to show that you can handle the course material as directed. Paper assignments give you more than a topic to discuss—they ask you to do something with the topic. Keep reminding yourself of that. Be careful to avoid the other extreme as well: do not read more into the assignment than what is there.

Of course, your instructor has given you an assignment so that they will be able to assess your understanding of the course material and give you an appropriate grade. But there is more to it than that. Your instructor has tried to design a learning experience of some kind. Your instructor wants you to think about something in a particular way for a particular reason. If you read the course description at the beginning of your syllabus, review the assigned readings, and consider the assignment itself, you may begin to see the plan, purpose, or approach to the subject matter that your instructor has created for you. If you still aren’t sure of the assignment’s goals, try asking the instructor. For help with this, see our handout on getting feedback .

Given your instructor’s efforts, it helps to answer the question: What is my purpose in completing this assignment? Is it to gather research from a variety of outside sources and present a coherent picture? Is it to take material I have been learning in class and apply it to a new situation? Is it to prove a point one way or another? Key words from the assignment can help you figure this out. Look for key terms in the form of active verbs that tell you what to do.

Key Terms: Finding Those Active Verbs

Here are some common key words and definitions to help you think about assignment terms:

Information words Ask you to demonstrate what you know about the subject, such as who, what, when, where, how, and why.

• define —give the subject’s meaning (according to someone or something). Sometimes you have to give more than one view on the subject’s meaning
• describe —provide details about the subject by answering question words (such as who, what, when, where, how, and why); you might also give details related to the five senses (what you see, hear, feel, taste, and smell)
• explain —give reasons why or examples of how something happened
• illustrate —give descriptive examples of the subject and show how each is connected with the subject
• summarize —briefly list the important ideas you learned about the subject
• trace —outline how something has changed or developed from an earlier time to its current form
• research —gather material from outside sources about the subject, often with the implication or requirement that you will analyze what you have found

Relation words Ask you to demonstrate how things are connected.

• compare —show how two or more things are similar (and, sometimes, different)
• contrast —show how two or more things are dissimilar
• apply—use details that you’ve been given to demonstrate how an idea, theory, or concept works in a particular situation
• cause —show how one event or series of events made something else happen
• relate —show or describe the connections between things

Interpretation words Ask you to defend ideas of your own about the subject. Do not see these words as requesting opinion alone (unless the assignment specifically says so), but as requiring opinion that is supported by concrete evidence. Remember examples, principles, definitions, or concepts from class or research and use them in your interpretation.

• assess —summarize your opinion of the subject and measure it against something
• prove, justify —give reasons or examples to demonstrate how or why something is the truth
• evaluate, respond —state your opinion of the subject as good, bad, or some combination of the two, with examples and reasons
• support —give reasons or evidence for something you believe (be sure to state clearly what it is that you believe)
• synthesize —put two or more things together that have not been put together in class or in your readings before; do not just summarize one and then the other and say that they are similar or different—you must provide a reason for putting them together that runs all the way through the paper
• analyze —determine how individual parts create or relate to the whole, figure out how something works, what it might mean, or why it is important
• argue —take a side and defend it with evidence against the other side

More Clues to Your Purpose As you read the assignment, think about what the teacher does in class:

• What kinds of textbooks or coursepack did your instructor choose for the course—ones that provide background information, explain theories or perspectives, or argue a point of view?
• In lecture, does your instructor ask your opinion, try to prove their point of view, or use keywords that show up again in the assignment?
• What kinds of assignments are typical in this discipline? Social science classes often expect more research. Humanities classes thrive on interpretation and analysis.
• How do the assignments, readings, and lectures work together in the course? Instructors spend time designing courses, sometimes even arguing with their peers about the most effective course materials. Figuring out the overall design to the course will help you understand what each assignment is meant to achieve.

Now, what about your reader? Most undergraduates think of their audience as the instructor. True, your instructor is a good person to keep in mind as you write. But for the purposes of a good paper, think of your audience as someone like your roommate: smart enough to understand a clear, logical argument, but not someone who already knows exactly what is going on in your particular paper. Remember, even if the instructor knows everything there is to know about your paper topic, they still have to read your paper and assess your understanding. In other words, teach the material to your reader.

Aiming a paper at your audience happens in two ways: you make decisions about the tone and the level of information you want to convey.

• Tone means the “voice” of your paper. Should you be chatty, formal, or objective? Usually you will find some happy medium—you do not want to alienate your reader by sounding condescending or superior, but you do not want to, um, like, totally wig on the man, you know? Eschew ostentatious erudition: some students think the way to sound academic is to use big words. Be careful—you can sound ridiculous, especially if you use the wrong big words.
• The level of information you use depends on who you think your audience is. If you imagine your audience as your instructor and they already know everything you have to say, you may find yourself leaving out key information that can cause your argument to be unconvincing and illogical. But you do not have to explain every single word or issue. If you are telling your roommate what happened on your favorite science fiction TV show last night, you do not say, “First a dark-haired white man of average height, wearing a suit and carrying a flashlight, walked into the room. Then a purple alien with fifteen arms and at least three eyes turned around. Then the man smiled slightly. In the background, you could hear a clock ticking. The room was fairly dark and had at least two windows that I saw.” You also do not say, “This guy found some aliens. The end.” Find some balance of useful details that support your main point.

You’ll find a much more detailed discussion of these concepts in our handout on audience .

The Grim Truth

With a few exceptions (including some lab and ethnography reports), you are probably being asked to make an argument. You must convince your audience. It is easy to forget this aim when you are researching and writing; as you become involved in your subject matter, you may become enmeshed in the details and focus on learning or simply telling the information you have found. You need to do more than just repeat what you have read. Your writing should have a point, and you should be able to say it in a sentence. Sometimes instructors call this sentence a “thesis” or a “claim.”

So, if your instructor tells you to write about some aspect of oral hygiene, you do not want to just list: “First, you brush your teeth with a soft brush and some peanut butter. Then, you floss with unwaxed, bologna-flavored string. Finally, gargle with bourbon.” Instead, you could say, “Of all the oral cleaning methods, sandblasting removes the most plaque. Therefore it should be recommended by the American Dental Association.” Or, “From an aesthetic perspective, moldy teeth can be quite charming. However, their joys are short-lived.”

Convincing the reader of your argument is the goal of academic writing. It doesn’t have to say “argument” anywhere in the assignment for you to need one. Look at the assignment and think about what kind of argument you could make about it instead of just seeing it as a checklist of information you have to present. For help with understanding the role of argument in academic writing, see our handout on argument .

What kind of evidence do you need?

There are many kinds of evidence, and what type of evidence will work for your assignment can depend on several factors–the discipline, the parameters of the assignment, and your instructor’s preference. Should you use statistics? Historical examples? Do you need to conduct your own experiment? Can you rely on personal experience? See our handout on evidence for suggestions on how to use evidence appropriately.

Make sure you are clear about this part of the assignment, because your use of evidence will be crucial in writing a successful paper. You are not just learning how to argue; you are learning how to argue with specific types of materials and ideas. Ask your instructor what counts as acceptable evidence. You can also ask a librarian for help. No matter what kind of evidence you use, be sure to cite it correctly—see the UNC Libraries citation tutorial .

You cannot always tell from the assignment just what sort of writing style your instructor expects. The instructor may be really laid back in class but still expect you to sound formal in writing. Or the instructor may be fairly formal in class and ask you to write a reflection paper where you need to use “I” and speak from your own experience.

Try to avoid false associations of a particular field with a style (“art historians like wacky creativity,” or “political scientists are boring and just give facts”) and look instead to the types of readings you have been given in class. No one expects you to write like Plato—just use the readings as a guide for what is standard or preferable to your instructor. When in doubt, ask your instructor about the level of formality they expect.

No matter what field you are writing for or what facts you are including, if you do not write so that your reader can understand your main idea, you have wasted your time. So make clarity your main goal. For specific help with style, see our handout on style .

Technical details about the assignment

The technical information you are given in an assignment always seems like the easy part. This section can actually give you lots of little hints about approaching the task. Find out if elements such as page length and citation format (see the UNC Libraries citation tutorial ) are negotiable. Some professors do not have strong preferences as long as you are consistent and fully answer the assignment. Some professors are very specific and will deduct big points for deviations.

Usually, the page length tells you something important: The instructor thinks the size of the paper is appropriate to the assignment’s parameters. In plain English, your instructor is telling you how many pages it should take for you to answer the question as fully as you are expected to. So if an assignment is two pages long, you cannot pad your paper with examples or reword your main idea several times. Hit your one point early, defend it with the clearest example, and finish quickly. If an assignment is ten pages long, you can be more complex in your main points and examples—and if you can only produce five pages for that assignment, you need to see someone for help—as soon as possible.

Tricks that don’t work

Your instructors are not fooled when you:

• spend more time on the cover page than the essay —graphics, cool binders, and cute titles are no replacement for a well-written paper.
• use huge fonts, wide margins, or extra spacing to pad the page length —these tricks are immediately obvious to the eye. Most instructors use the same word processor you do. They know what’s possible. Such tactics are especially damning when the instructor has a stack of 60 papers to grade and yours is the only one that low-flying airplane pilots could read.
• use a paper from another class that covered “sort of similar” material . Again, the instructor has a particular task for you to fulfill in the assignment that usually relates to course material and lectures. Your other paper may not cover this material, and turning in the same paper for more than one course may constitute an Honor Code violation . Ask the instructor—it can’t hurt.
• get all wacky and “creative” before you answer the question . Showing that you are able to think beyond the boundaries of a simple assignment can be good, but you must do what the assignment calls for first. Again, check with your instructor. A humorous tone can be refreshing for someone grading a stack of papers, but it will not get you a good grade if you have not fulfilled the task.

Critical reading of assignments leads to skills in other types of reading and writing. If you get good at figuring out what the real goals of assignments are, you are going to be better at understanding the goals of all of your classes and fields of study.

Question 1 (Interpreting parameters when features are correlated) #

Generate a simulated data set as follows:

Consdier the data generated above and the model lm(y ~ x1 + x2) ? What are the true \(\beta_0, \beta_1, \beta_2\) ? What is the true \(\sigma^2\) ?

Create a scatterplot with x1 on the X-axis and x2 on the Y-axis. What is the sample correlation of x1 and x2 ? (Use cor )

Fit the model lm(y ~ x1 + x2) . At level 5%, can you reject the null hypothesis \(H_0:\beta_{\texttt x1}=0\) ? How about the null hypothesis \(H_0:\beta_{\texttt x2}=0\) ?

Fit the model lm(y ~ x1) . At level 5%, can you reject the null hypothesis \(H_0:\beta_{\texttt x1}=0\) ? Next, fit the model lm(y ~ x2) . At level 5%, can you reject the null hypothesis \(H_0:\beta_{\texttt x2}=0\) ?

Do the results of parts 3. & 4. contradict each other? Explain.

In this part, we’ll add a single point to the data set to explore outliers and high leverage. We’ll call a point an outlier if its residual is at least 3 in absolute value, and we’ll say a point has high leverage if its hatvalues score is at least 0.2. For each of A.-C. compute the residual and hatvalues score.

A. Pick a point (i.e. values for (x1,x2,y) ) that would be an outlier relative to the other 100 points but not a point of high leverage.

B. Pick a point (i.e. values for (x1,x2,y) ) that would be a point of high leverage relative to the other 100 points but not an outlier.

C. Pick a point (i.e. values for (x1,x2,y) ) that would be both a point of high leverage and an outlier relative to the other 100 points.

Question 2 (Model selection for multiple linear regression) #

Use the Carseats data we saw in Assignment 3 for this problem.

Fit a full model Sales ~ . to the data.

Extract the design matrix from your model in 1., discarding the column for the intercept.

Use leaps to select a model using adjusted \(R^2\) as a criterion, storing the 5 best models of each size.

Use leaps to select a model using Mallow’s \(C_p\) as a criterion, storing the 5 best models of each size.

Use step to select a model using direction='forward' starting from Sales ~ 1 with the upper model being the model in 1. Do the models in 3., 4. and 5. agree?

Make a plot of \(C_p\) versus model size. Is your selected model clearly better than all others or are there other models of similar quality?

Question 3 #

Consider the Wage data we saw in Assignment 1.

Create an outcome variable high which is TRUE if wage > 250 and FALSE otherwise.

Fit a logistic regression model high with features maritl , age , health , health_ins , education and race .

At a 5% level, test the null hypothesis that the effect of maritl is 0 in the model in part 2.

Split the data into two sets of equal size using this snippet of code to form a half for model selection and a second half for inference. We’ll focus on students with at least HS :

Using subset=selection , select a model using forward selection using step with the largest model being the model in 2. Call this model selected.glm

Fit the same model selected in 5. on subset=inference . Call this model split.glm . Compare the summary() of split.glm and selected.glm . In terms of overall signficance of estimated effects, would your conclusions be very different between selected.glm and split.glm ? Do any effects that were significant at level 5% in the select.glm switch to not significant in split.glm ?

Democrat Senator Bob Menendez of New Jersey, who sidestepped corruption charges due to a mistrial in 2017, is under federal indictment again, and the timing couldn’t be worse for Senate Democrats trying to maintain control of the chamber. Gregory Krieg is covering the Menendez trial for CNN and he’ll highlight this blockbuster case that’s been completely overshadowed by the Trump show next door.

Screening for Autism Spectrum Disorder

• Diagnosing autism spectrum disorder (ASD) can be difficult because there is no medical test, such as a blood test, to diagnose the disorder. Doctors look at the child's developmental history and behavior to make a diagnosis.
• Diagnosing ASD involves several steps.
• Some people with ASD are not diagnosed until they are adolescents or adults. This delay means that they might not get the early help they need.

Developmental monitoring

Developmental monitoring is an active, ongoing process of watching a child grow and encouraging conversations between parents and providers about a child's skills and abilities. Developmental monitoring involves observing how your child grows and whether your child meets the typical developmental milestones, or skills that most children reach by a certain age, in playing, learning, speaking, behaving, and moving.

Parents, grandparents, early childhood education providers, and other caregivers can participate in developmental monitoring. CDC's Learn the Signs. Act Early. program has developed free materials, including CDC's Milestone Tracker app, to help parents and providers work together to monitor your child's development and know when there might be a concern and if more screening is needed. You can use a brief checklist of milestones to see how your child is developing. If you notice that your child is not meeting milestones, talk with your doctor or nurse about your concerns and ask about developmental screening. Learn more about CDC's Milestone Tracker app, milestone checklists, and other parent materials.

When you take your child to a well visit, your child's doctor or nurse will also do developmental monitoring. The doctor or nurse might ask you questions about your child's development or will talk and play with your child to see if they are developing and meeting milestones.

Your child's doctor or nurse may also ask about your child's family history. Be sure to let the doctor or nurse know about any conditions that your child's family members have, including ASD, learning disorders, intellectual disability, or attention-deficit/hyperactivity disorder (ADHD).

Developmental screening

Developmental screening takes a closer look at how your child is developing.

Developmental screening is more formal than developmental monitoring. It is a regular part of some well-child visits even if there is not a known concern.

The American Academy of Pediatrics (AAP) recommends developmental and behavioral screening for all children during regular well-child visits at these ages:

In addition, AAP recommends that all children be screened specifically for ASD during regular well-child visits at these ages:

Did you know?‎

Screening questionnaires and checklists are based on research that compares your child with other children of the same age. Questions may ask about language, movement, and thinking skills, as a well as behaviors and emotions.

Developmental screening can be done by a doctor or nurse, or other professionals in healthcare, community, or school settings. Your doctor may ask you to complete a questionnaire as part of the screening process. Screening at times other than the recommended ages should be done if you or your doctor have a concern. Additional screening should also be done if a child is at high risk for ASD (for example, having a sibling or other family member with ASD) or if behaviors sometimes associated with ASD are present.

If your child’s healthcare provider does not periodically check your child with a developmental screening test, you can ask that it be done.

Developmental diagnosis

Diagnosing children with ASD as early as possible is important to make sure children receive the services and supports they need to reach their full potential. 2 There are several steps in this process.

A brief test using a screening tool does not provide a diagnosis, but it can indicate whether a child is on the right development track or if a specialist should take a closer look. If the screening tool identifies an area of concern, a formal developmental evaluation may be needed.

This formal evaluation is a more in-depth look at a child's development and is usually done by a trained specialist such as a developmental pediatrician, child psychologist, speech-language pathologist, or occupational therapist. The results of a formal developmental evaluation can also show whether your child needs early intervention services. In some cases, the specialist might recommend genetic counseling and testing for your child.

The specialist may observe the child and give the child a structured test, ask the parents or caregivers questions, or ask the parents or caregivers to fill out questionnaires. The results of this formal evaluation highlight your child's strengths and challenges and can inform whether they meet criteria for a developmental diagnosis.

Copilot+ PCs are a new class of Windows 11 PCs that are powered by a turbocharged neural processing unit (NPU)—a specialized computer chip for AI-intensive processes like real-time translations and image generation—that can perform more than 40 trillion operations per second (TOPS).

Copilot+ PC experiences are advanced AI features unique to Copilot+ PCs that accelerate your productivity and creativity: Recall, Cocreator, Windows Studio Effects, Super Resolution, and live Captions.

These features require powerful neural processing units (NPUs)—a specialized computer chip for AI-intensive processes—that are unique to the Copilot+ PC class of devices.

Available starting on June 18, Copilot+ PCs running a Snapdragon X Series processor will have Copilot+ PC experiences pre-installed. You should be able to access all Copilot+ PC experiences after you start your device for the first time. To use Cocreator for the first time, you will need to click on the feature, acknowledge you want to use AI to create art, and download the AI model. We are continuing to update and enhance our Copilot+ PC experiences, so you may need to download and install the latest Windows Updates to get new features and experiences available for these devices.

Everyone who uses a computer. The unique experiences that come with Copilot+ PCs were made to accelerate the productivity and creativity of all users.

Copilot+ PCs are available in most global markets.

You can purchase them online or at a local authorized retailer.

Copilot+ PC models will start at $999. This is an estimated retail price; actual prices may vary.

A valuable resource to you may be the " Help me choose a PC " tool. This will help you find devices that best fit your needs, lifestyle, and budget.

Yes. We are partnering with Intel and AMD to bring Copilot+ PC experiences to PCs with their processors in the future.

Copilot+ PC features

You can use Recall on Copilot+ PCs to find the content you have viewed on your device. Recall is currently in preview status; during this phase, we will collect customer feedback, develop more controls for enterprise customers to manage and govern Recall data, and improve the overall experience for users. On devices that are not powered by a Snapdragon® X Series processor, installation of a Windows update will be required to run Recall. Recall is currently optimized for select languages, including English, Chinese (simplified), French, German, Japanese, and Spanish. This means Recall is able to retrieve snapshots from your PC’s timeline based on more sophisticated searches in these languages. During the preview phase, we will enhance optimization for additional languages. Recall can also retrieve snapshots from your PC’s timeline based on text-to-text searches in more than 160 languages.

Recall uses Copilot+ PC advanced processing capabilities to take images of your active screen every few seconds. The snapshots are encrypted and saved on your PC’s hard drive. You can use Recall to locate the content you have viewed on your PC using search or on a timeline bar that allows you to scroll through your snapshots. Once you find the snapshot that you were looking for in Recall, it will be analyzed and offer you options to interact with the content. Recall will also enable you to open the snapshot in the original application in which it was created, and, as Recall is refined over time, it will open the actual source document, website, or email in a screenshot. This functionality will be improved during Recall’s preview phase. Copilot+ PC storage size determines the number of snapshots that Recall can take and store. The minimum hard drive space needed to run Recall is 256 GB, and 50 GB of space must be available. The default allocation for Recall on a device with 256 GB will be 25 GB, which can store approximately 3 months of snapshots. You can increase the storage allocation for Recall in your PC Settings. Old snapshots will be deleted once you use your allocated storage, allowing new ones to be stored.

Recall is a key part of what makes Copilot+ PCs special, and Microsoft built privacy into Recall’s design from the ground up. On Copilot+ PCs powered by a Snapdragon® X Series processor, you will see the Recall taskbar icon after you first activate your device. You can use that icon to open Recall’s settings and make choices about what snapshots Recall collects and stores on your device. You can limit which snapshots Recall collects; for example, you can select specific apps or websites visited in a supported browser to filter out of your snapshots. In addition, you can pause snapshots on demand from the Recall icon in the system tray, clear some or all snapshots that have been stored, or delete all the snapshots from your device. Recall also does not take snapshots of certain kinds of content, including InPrivate web browsing sessions in Microsoft Edge. It treats material protected with digital rights management (DRM) similarly; like other Windows apps such as the Snipping Tool, Recall will not store DRM content. Note that Recall does not perform content moderation. It will not hide information such as passwords or financial account numbers. That data may be in snapshots that are stored on your device, especially when sites do not follow standard internet protocols like cloaking password entry.

Recall snapshots are kept on Copilot+ PCs themselves, on the local hard disk, and are protected using data encryption on your device and (if you have Windows 11 Pro or an enterprise Windows 11 SKU) BitLocker. Recall screenshots are only linked to a specific user profile and Recall does not share them with other users, make them available for Microsoft to view, or use them for targeting advertisements. Screenshots are only available to the person whose profile was used to sign in to the device. If two people share a device with different profiles they will not be able to access each other’s screenshots. If they use the same profile to sign-in to the device then they will share a screenshot history. Otherwise, Recall screenshots are not available to other users or accessed by other applications or services.

Live captions allow you to translate audio and video content into English subtitles from 44 languages: Arabic, Basque, Bosnian, Bulgarian, Chinese (Cantonese), Chinese (Mandarin), Czech, Danish, Dutch, English, Estonian, Finnish, French, Galician, German, Greek, Hindi, Hungarian, Indonesian, Irish, Italian, Japanese, Korean, Latvian, Lithuanian, Macedonian, Maltese, Norwegian, Pashto, Polish, Portuguese, Romanian, Russian, Slovak, Serbian, Slovenian, Somali, Spanish, Swedish, Thai, Turkish, Ukrainian, Vietnamese, and Welsh.

With Cocreator, you can use text or image prompts to generate an interpretation of your vision. Cocreator works by translating your prompt into English, and prompts in Standard American English are likely to generate the most accurate images. Prompts in other languages may not work as well.

Auto super resolution (Auto SR) seamlessly integrates with Windows to automatically enhance the frame rates of existing games in real-time while also providing detailed visuals on screen, offering a balance that exceeds what your PC hardware can achieve on its own. At initial launch, this feature will be exclusive to Copilot+ PCs equipped with a Qualcomm Snapdragon® X Elite processor and a curated set of games that can be found at https://www.worksonwoa.com/ a third-party open-source site that Microsoft has contributed compatibility data to.

Windows Studio Effects is the collective name of AI-powered video call effects that are available on Copilot+ PCs and select Windows 11 devices with compatible NPUs. They include Creative Filters, Portrait Light, Eye Contact, Portrait Blur and Voice Focus, and all involve modifying the outbound and inbound audio and video feed to enhance communication. Some Windows Studio Effects features, like Voice Focus and Portrait Blur, are unique to Copilot+ PCs.

• Screens simulated, subject to change.
• 1 Currently supports translation for video and audio subtitles into English from 40+ languages.
• 2 Optimized for select languages (English, Chinese (Simplified), French, German, Japanese, and Spanish). Content-based and storage limitations apply.
• 4 Battery life varies significantly based on device, settings, usage, and other factors.
• 5 Optimized for English text prompts.
• 11 Surface battery life varies significantly based on usage, network and feature configuration, signal strength, settings, and other factors. See Surface battery testing and estimated performance - Microsoft Support for details.

Jennifer Lopez shuts down question about her marriage to Ben Affleck during movie press tour

Jennifer Lopez quickly shut down a question about her marriage to Ben Affleck while promoting her movie “Atlas” this week.

The megastar appeared unfazed at the press event in Mexico City on Wednesday when asked about reports that the pair were rumored to be living separately .

During a question-and-answer session, the singer was asked by someone in the crowd: “Your divorce with Ben Affleck is real? What is the truth?” according to a video shared on X by Glamour México y Latinoamérica.

Lopez was onstage with co-star Simu Liu, who quickly intervened by saying: “OK, we’re not doing that.”

Lopez gave the questioner a smile, then leaned in and said: “You know better than that.”

Another video shared on Instagram by El Gordo y La Flaca showed that the interview ended after that question.

The sci-fi film “Atlas,” which is set to release Friday on Netflix, stars Lopez, Liu, Sterling K. Brown and Lana Parrilla.

Lopez and Affleck, who were engaged in the early 2000s but broke up and spent 17 years apart, rekindled their relationship in 2021 and tied the knot in July 2022.
