Can I take a course at HippoCampus for credit?

How do i enroll in a course at hippocampus, are there any fees to take your courses, how do i make a comment or ask a question, how do i get individual help with my homework assignment, how can i use hippocampus in my classroom, how can i use hippocampus in my home school, can i use the resources you have available for my homeschoolers, is there a script, app, or something that can be used to track student use of hippocampus, can i download the video, can i change the size of the video window, what if my page scroll bars or "submit" button are not showing, i can't find closed captioning. isn't this a violation of 504/508 of the federal rehabilitation act, where does the content from your site come from, there is an error in the multimedia presentation. can you fix it, how do i report a course errata item, why are there answer keys available to the students for the end-of-chapter tests, where are the answers to the review questions, the audio in some videos within the religion course is problematic. can you fix it, why aren't the lab sections in environmental science appearing, hippocampus and advanced placement (ap)*, how are homeschoolers using hippocampus for ap what about dante and clep, can schools order and administer ap exams without completing the ap course audit, are the courses at hippocampus ap approved.

We are a non-profit organization and provide the content at our websites for self-improvement only as part of our mission. You cannot get credit for it since we are not a school.

We are not a school, so you cannot enroll in a course, but individuals are welcome to use the materials for free as study aids.

There is no charge for individual users at HippoCampus.

You can email a comment or question directly to nroc.org/contact , or you can click the "Comments and Questions" icon in the Media Window control bar. The icon looks like a small speech bubble.

While we understand that you may need assistance with your homework, we cannot provide the answers to your problems or individual assistance. We hope you can use our website as a tool to help you learn the subject matter so that you can find the answers.

More than half the use of HippoCampus occurs during classroom hours, when teachers go online to project topic lectures and show simulations launched from the HippoCampus site.

HippoCampus is not a credit-granting organization, and does not monitor, grade, or give transcripts to anyone using the site. However, many home schooling families have used HippoCampus content to supplement or guide their home curriculum, and we welcome them as users. HippoCampus is made possible by the members of The NROC Project, and many NROC members offer credit for courses that contain HippoCampus content.

Yes, although homeschoolers should realize that the content presented is not a complete course. The content is intended to have an instructor to provide supplemental assignments and instruction. Since there is no teacher available through HippoCampus, the parent must take the role of instructor.

No. Our Terms of Use specify that HippoCampus is provided by The NROC Project for personal enrichment and individual instructor use only. The unlicensed use of this content by educational organizations or commercial vendors is prohibited.

Unfortunately, there is no way to download the video from our website. As an individual user, however, you may create a custom HippoCampus page and then link to an individual topic. After you have created your custom page, there will be buttons in the upper right corner that allow you to view the text version (when available), bookmark, or link to the topic.

Yes, in multiple ways. First, there is a "maximize" button beneath the bottom left corner of the Media Window which will widen the screen. There is also a "hide column" button beneath the first column of content in the Browse Topics tab. These can be used simultaneously or independently. For some content, such as that from Khan Academy, a small button in the lower right corner of the media control bar allows the content to be shown full screen. For other content, such as Algebra I--An Open Course, right-clicking the mouse over the video content will open a menu that offers Full Screen as an option.

Your screen resolution may be set too low. The Algebra course requires that your screen resolution be at 1024x768 or higher. Most of the other content requires a resolution of 600x800 or higher.

Much, but not all, of the content at HippoCampus is closed captioned. Section 508 of the Rehabilitation Act to requires Federal agencies to make their electronic and information technology accessible to people with disabilities. The law applies to all Federal agencies when they develop, procure, maintain, or use electronic and information technology. The educational resources provided at HippoCampus.org were not procured by, and are not made available through, a Federal agency, so the law is not applicable to the content at this website.

All the content we provide at HippoCampus is created by other educational institutions and companies and contributed to us to distribute as part of our non-profit mission.

Due to the complexity of modifying the multimedia content, we cannot always correct errors within the video presentations. There is an Errata icon that appears with any topics in which a known error has been identified. We encourage our users to report any errors they discover so that we can notify everyone of the problem. There is also an errata sheet available for some courses if you select "Launch a Full Course."

Use the "Comments and Questions" feature in the Media Window control bar. The icon looks like a small speech bubble, and allows you to send in a description of the error directly from the relevant piece of media. Or you can send an email to nroc.org/contact . Please describe the issue as precisely as possible. If you provide your email address, we will inform you about the correction process, or ask any follow-up questions necessary to clarify the report.

The tests that appear on our website are intended as open tests for self-assessment only. They are not intended to be secure tests since the answers are freely available at several websites.

There are answer keys available for the chapter tests but not for the review questions. The answer keys for the chapter tests are located as a link right under the chapter test link.

This is a problem that was in the original content we received from the course developer. We have no way of fixing this at this time.

The Environmental Science labs require you to have Java installed on your computer. You can get the latest version at http://www.java.com/en/download/manual.jsp

We know a lot of homeschoolers use HippoCampus. We are often asked if homeschoolers can study the content at HippoCampus and then just take and pass the AP exam. HippoCampus courses were designed to address the AP College Board criteria. However, as with any teaching resource, they should not be considered a singular solution, but can be used as a good foundation for an AP teaching curriculum. The courses at HippoCampus have not currently been mapped to the CLEP and DANTE tests. If you wish to receive college credit for taking an AP course, most colleges will require that the courses have been approved by the College Board. Schools wishing to give their students AP credit must go through the AP audit process. The same is true for homeschoolers. The AP Course Ledger section below gives more information about the audit process. AP Course Ledger The AP Course Ledger is a comprehensive and public registry of all courses authorized to use the AP label on student transcripts. The Ledger is an annual and culminating product of the AP Course Audit, a process by which college faculty confirm that courses submitted by AP teachers and schools provide students with the essential elements of a college level experience. As an exclusively Web-based registry, the Ledger is published annually in November and updated weekly throughout the academic year to reflect newly authorized courses. Here is a link to AP Audit information, (and you can find other links on this page to various other resources): http://www.collegeboard.com/html/apcourseaudit/

Yes, the AP Course Audit is only required for schools desiring to: -- use the "AP" designation on students' transcripts -- be listed in the ledger of authorized AP courses provided each fall to college and university admissions offices and the public. Schools that simply offer the AP Exam as an opportunity for their students to earn college credit, without actually labeling the school's courses "AP" on students' transcripts, do not need to participate in the AP Course Audit, and can continue offering AP Exams to their students.

Our AP content is a good resource to help students prepare for AP exams. However, while we provide content resources, we do not have instructors who teach the courses. In order to be authorized by the College Board and put in the AP Course Ledger, an instructor must submit a syllabus for the course. While we do not have instructors who teach our courses, we do have NROC member schools that teach the courses for credit and they have been approved through the AP College Board. *AP, Advanced Placement and Advanced Placement Program are registered trademarks of the College Board, which was not involved in the production of, and does not endorse, this content.

Homework Help & Tutoring

Our name 24HourAnswers means you can submit work 24 hours a day - it doesn't mean we can help you master what you need to know in 24 hours. If you make arrangements in advance, and if you are a very fast learner, then yes, we may be able to help you achieve your goals in 24 hours. Remember, high quality, customized help that's tailored around the needs of each individual student takes time to achieve. You deserve nothing less than the best, so give us the time we need to give you the best.

If you need assistance with old exams in order to prepare for an upcoming test, we can definitely help. We can't work with you on current exams, quizzes, or tests unless you tell us in writing that you have permission to do so. This is not usually the case, however.

We do not have monthly fees or minimum payments, and there are no hidden costs. Instead, the price is unique for every work order you submit. For tutoring and homework help, the price depends on many factors that include the length of the session, level of work difficulty, level of expertise of the tutor, and amount of time available before the deadline. You will be given a price up front and there is no obligation for you to pay. Homework library items have individual set prices.

We accept credit cards, debit cards, PayPal, Venmo, ApplePay, and GooglePay.

Sat / act prep online guides and tips, the 5 best homework help websites (free and paid).

Other High School , General Education

Listen: we know homework isn’t fun, but it is a good way to reinforce the ideas and concepts you’ve learned in class. But what if you’re really struggling with your homework assignments?

If you’ve looked online for a little extra help with your take-home assignments, you’ve probably stumbled across websites claiming to provide the homework help and answers students need to succeed . But can homework help sites really make a difference? And if so, which are the best homework help websites you can use? 

Below, we answer these questions and more about homework help websites–free and paid. We’ll go over: 

• The basics of homework help websites
• The cost of homework help websites 
• The five best homework websites out there 
• The pros and cons of using these websites for homework help 
• The line between “learning” and “cheating” when using online homework help 
• Tips for getting the most out of a homework help website

So let’s get started! 

The Basics About Homework Help Websites–Free and Paid

Homework help websites are designed to help you complete your homework assignments, plain and simple. 

What Makes a Homework Help Site Worth Using

Most of the best sites allow users to ask questions and then provide an answer (or multiple possible answers) and explanation in seconds. In some instances, you can even send a photo of a particular assignment or problem instead of typing the whole thing out! 

Homework help sites also offer more than just help answering homework questions. Common services provided are Q&A with experts, educational videos, lectures, practice tests and quizzes, learning modules, math solving tools, and proofreading help. Homework help sites can also provide textbook solutions (i.e. answers to problems in tons of different textbooks your school might be using), one-on-one tutoring, and peer-to-peer platforms that allow you to discuss subjects you’re learning about with your fellow students. 

And best of all, nearly all of them offer their services 24/7, including tutoring! 

What You Should Should Look Out For

When it comes to homework help, there are lots–and we mean lots –of scam sites out there willing to prey on desperate students. Before you sign up for any service, make sure you read reviews to ensure you’re working with a legitimate company. 

A word to the wise: the more a company advertises help that veers into the territory of cheating, the more likely it is to be a scam. The best homework help websites are going to help you learn the concepts you’ll need to successfully complete your homework on your own. (We’ll go over the difference between “homework help” and “cheating” a little later!) 

You don't need a golden piggy bank to use homework help websites. Some provide low or no cost help for students like you!

How Expensive Are the Best Homework Help Websites?

First of all, just because a homework help site costs money doesn’t mean it’s a good service. Likewise, just because a homework help website is free doesn’t mean the help isn’t high quality. To find the best websites, you have to take a close look at the quality and types of information they provide! 

When it comes to paid homework help services, the prices vary pretty widely depending on the amount of services you want to subscribe to. Subscriptions can cost anywhere from $2 to $150 dollars per month, with the most expensive services offering several hours of one-on-one tutoring with a subject expert per month.

The 5 Best Homework Help Websites 

So, what is the best homework help website you can use? The answer is that it depends on what you need help with. 

The best homework help websites are the ones that are reliable and help you learn the material. They don’t just provide answers to homework questions–they actually help you learn the material. 

That’s why we’ve broken down our favorite websites into categories based on who they’re best for . For instance, the best website for people struggling with math might not work for someone who needs a little extra help with science, and vice versa. 

Keep reading to find the best homework help website for you! 

Best Free Homework Help Site: Khan Academy

• Price: Free!
• Best for: Practicing tough material 

Not only is Khan Academy free, but it’s full of information and can be personalized to suit your needs. When you set up your account , you choose which courses you need to study, and Khan Academy sets up a personal dashboard of instructional videos, practice exercises, and quizzes –with both correct and incorrect answer explanations–so you can learn at your own pace. 

As an added bonus, it covers more course topics than many other homework help sites, including several AP classes.

Runner Up: Brainly.com offers a free service that allows you to type in questions and get answers and explanations from experts. The downside is that you’re limited to two answers per question and have to watch ads. 

Best Paid Homework Help Site: Chegg

• Price: $14.95 to $19.95 per month
• Best for: 24/7 homework assistance  

This service has three main parts . The first is Chegg Study, which includes textbook solutions, Q&A with subject experts, flashcards, video explanations, a math solver, and writing help. The resources are thorough, and reviewers state that Chegg answers homework questions quickly and accurately no matter when you submit them.  

Chegg also offers textbook rentals for students who need access to textbooks outside of their classroom. Finally, Chegg offers Internship and Career Advice for students who are preparing to graduate and may need a little extra help with the transition out of high school. 

Another great feature Chegg provides is a selection of free articles geared towards helping with general life skills, like coping with stress and saving money. Chegg’s learning modules are comprehensive, and they feature solutions to the problems in tons of different textbooks in a wide variety of subjects. 

Runner Up: Bartleby offers basically the same services as Chegg for $14.99 per month. The reason it didn’t rank as the best is based on customer reviews that say user questions aren’t answered quite as quickly on this site as on Chegg. Otherwise, this is also a solid choice!

Best Site for Math Homework Help: Photomath

• Price: Free (or $59.99 per year for premium services) 
• Best for: Explaining solutions to math problems

This site allows you to t ake a picture of a math problem, and instantly pulls up a step-by-step solution, as well as a detailed explanation of the concept. Photomath also includes animated videos that break down mathematical concepts to help you better understand and remember them. 

The basic service is free, but for an additional fee you can get extra study tools and learn additional strategies for solving common math problems.

Runner Up: KhanAcademy offers in-depth tutorials that cover complex math topics for free, but you won’t get the same tailored help (and answers!) that Photomath offers. 

Best Site for English Homework Help: Princeton Review Academic Tutoring

• Price: $40 to $153 per month, depending on how many hours of tutoring you want 
• Best for: Comprehensive and personalized reading and writing help 

While sites like Grammarly and Sparknotes help you by either proofreading what you write via an algorithm or providing book summaries, Princeton Review’s tutors provide in-depth help with vocabulary, literature, essay writing and development, proofreading, and reading comprehension. And unlike other services, you’ll have the chance to work with a real person to get help. 

The best part is that you can get on-demand English (and ESL) tutoring from experts 24/7. That means you can get help whenever you need it, even if you’re pulling an all-nighter! 

This is by far the most expensive homework site on this list, so you’ll need to really think about what you need out of a homework help website before you commit. One added benefit is that the subscription covers over 80 other subjects, including AP classes, which can make it a good value if you need lots of help!  

Best Site for STEM Homework Help: Studypool

• Best for: Science homework help
• Price: Varies; you’ll pay for each question you submit

When it comes to science homework help, there aren’t a ton of great resources out there. The best of the bunch is Studypool, and while it has great reviews, there are some downsides as well. 

Let’s start with the good stuff. Studypool offers an interesting twist on the homework help formula. After you create a free account, you can submit your homework help questions, and tutors will submit bids to answer your questions. You’ll be able to select the tutor–and price point–that works for you, then you’ll pay to have your homework question answered. You can also pay a small fee to access notes, lectures, and other documents that top tutors have uploaded. 

The downside to Studypool is that the pricing is not transparent . There’s no way to plan for how much your homework help will cost, especially if you have lots of questions! Additionally, it’s not clear how tutors are selected, so you’ll need to be cautious when you choose who you’d like to answer your homework questions.  

What Are the Pros and Cons of Using Homework Help Sites?

Homework help websites can be a great resource if you’re struggling in a subject, or even if you just want to make sure that you’re really learning and understanding topics and ideas that you’re interested in. But, there are some possible drawbacks if you don’t use these sites responsibly. 

We’ll go over the good–and the not-so-good–aspects of getting online homework help below. 

3 Pros of Using Homework Help Websites 

First, let’s take a look at the benefits. 

#1: Better Grades Beyond Homework

This is a big one! Getting outside help with your studies can improve your understanding of concepts that you’re learning, which translates into better grades when you take tests or write essays. 

Remember: homework is designed to help reinforce the concepts you learned in class. If you just get easy answers without learning the material behind the problems, you may not have the tools you need to be successful on your class exams…or even standardized tests you’ll need to take for college. 

#2: Convenience

One of the main reasons that online homework help is appealing is because it’s flexible and convenient. You don’t have to go to a specific tutoring center while they’re open or stay after school to speak with your teacher. Instead, you can access helpful resources wherever you can access the internet, whenever you need them.

This is especially true if you tend to study at off hours because of your extracurriculars, work schedule, or family obligations. Sites that offer 24/7 tutoring can give you the extra help you need if you can’t access the free resources that are available at your school. 

#3: Variety

Not everyone learns the same way. Maybe you’re more of a visual learner, but your teacher mostly does lectures. Or maybe you learn best by listening and taking notes, but you’re expected to learn something just from reading the textbook . 

One of the best things about online homework help is that it comes in a variety of forms. The best homework help sites offer resources for all types of learners, including videos, practice activities, and even one-on-one discussions with real-life experts. 

This variety can also be a good thing if you just don’t really resonate with the way a concept is being explained (looking at you, math textbooks!).

Not so fast. There are cons to homework help websites, too. Get to know them below!

3 Cons of Using Homework Help Websites 

Now, let’s take a look at the drawbacks of online homework help. 

#1: Unreliable Info

This can be a real problem. In addition to all the really good homework help sites, there are a whole lot of disreputable or unreliable sites out there. The fact of the matter is that some homework help sites don’t necessarily hire people who are experts in the subjects they’re talking about. In those cases, you may not be getting the accurate, up-to-date, and thorough information you need.

Additionally, even the great sites may not be able to answer all of your homework questions. This is especially true if the site uses an algorithm or chatbot to help students…or if you’re enrolled in an advanced or college-level course. In these cases, working with your teacher or school-provided tutors are probably your best option. 

#2: No Clarification

This depends on the service you use, of course. But the majority of them provide free or low-cost help through pre-recorded videos. Watching videos or reading info online can definitely help you with your homework… but you can’t ask questions or get immediate feedback if you need it .

#3: Potential For Scamming 

Like we mentioned earlier, there are a lot of homework help websites out there, and lots of them are scams. The review comments we read covered everything from outdated or wrong information, to misleading claims about the help provided, to not allowing people to cancel their service after signing up. 

No matter which site you choose to use, make sure you research and read reviews before you sign up–especially if it’s a paid service! 

When Does “Help” Become “Cheating”?

Admittedly, whether using homework help websites constitutes cheating is a bit of a grey area. For instance, is it “help” when a friend reads your essay for history class and corrects your grammar, or is it “cheating”? The truth is, not everyone agrees on when “help” crosses the line into “cheating .” When in doubt, it can be a good idea to check with your teacher to see what they think about a particular type of help you want to get. 

That said, a general rule of thumb to keep in mind is to make sure that the assignment you turn in for credit is authentically yours . It needs to demonstrate your own thoughts and your own current abilities. Remember: the point of every homework assignment is to 1) help you learn something, and 2) show what you’ve learned. 

So if a service answers questions or writes essays for you, there’s a good chance using it constitutes cheating. 

Here’s an example that might help clarify the difference for you. Brainstorming essay ideas with others or looking online for inspiration is “help” as long as you write the essay yourself. Having someone read it and give you feedback about what you need to change is also help, provided you’re the one that makes the changes later. 

But copying all or part of an essay you find online or having someone write (or rewrite) the whole thing for you would be “cheating.” The same is true for other subjects. Ultimately, if you’re not generating your own work or your own answers, it’s probably cheating.

5 Tips for Finding the Best Homework Help Websites for You

Now that you know some of our favorite homework help websites, free and paid, you can start doing some additional research on your own to decide which services might work best for you! Here are some top tips for choosing a homework help website. 

Tip 1: Decide How You Learn Best 

Before you decide which site or sites you’re going to use for homework help, y ou should figure out what kind of learning style works for you the most. Are you a visual learner? Then choose a site that uses lots of videos to help explain concepts. If you know you learn best by actually doing tasks, choose a site that provides lots of practice exercises.

Tip 2: Determine Which Subjects You Need Help With

Just because a homework help site is good overall doesn’t mean that it’s equally good for every subject. If you only need help in math, choose a site that specializes in that area. But if history is where you’re struggling, a site that specializes in math won’t be much help. So make sure to choose a site that you know provides high-quality help in the areas you need it most. 

Tip 3: Decide How Much One-On-One Help You Need 

This is really about cost-effectiveness. If you learn well on your own by reading and watching videos, a free site like Khan Academy is a good choice. But if you need actual tutoring, or to be able to ask questions and get personalized answers from experts, a paid site that provides that kind of service may be a better option.

Tip 4: Set a Budget

If you decide you want to go with a paid homework help website, set a budget first . The prices for sites vary wildly, and the cost to use them can add up quick. 

Tip 5: Read the Reviews

Finally, it’s always a good idea to read actual reviews written by the people using these homework sites. You’ll learn the good, the bad, and the ugly of what the users’ experiences have been. This is especially true if you intend to subscribe to a paid service. You’ll want to make sure that users think it’s worth the price overall!

What’s Next?

If you want to get good grades on your homework, it’s a good idea to learn how to tackle it strategically. Our expert tips will help you get the most out of each assignment…and boost your grades in the process.

Doing well on homework assignments is just one part of getting good grades. We’ll teach you everything you need to know about getting great grades in high school in this article.

Of course, test grades can make or break your GPA, too. Here are 17 expert tips that’ll help you get the most out of your study prep before you take an exam.
