13 Free Online Sources to Help You Through School

Whether you’re struggling with a particular class or just want to expand what you know, these 13 sites can give you a library’s worth of information right from your laptop.

1. U.C. Berkeley Webcasts

Get podcasts and webcasts of current and archived courses at the University of California, Berkeley, and both live and on-demand webcasts of notable appearances, campus events, and prominent speakers and lectures.

2. MIT Open Courseware

Choose from over 1,700 courses spanning MIT’s entire curriculum, and download free lecture notes, exams, problem sets, labs, video lectures, video demonstrations, and more.

3. Wikipedia

Almost every significant event, person, place and thing has a page on the Wiki. Just remember that Wikipedia is a user-generated and user-monitored site, so what you’re reading may not necessarily have passed a thorough review for accuracy. Wikipedia’s a great place to start when you want to know more about pretty much anything, but you may not want to rely on it as the main reference source for your term paper.

4. Podcast Alley

A directory of over 36,000 podcasts, Podcast Alley lets you search for podcasts by key words or by category. Find hundreds of language-learning choices in the Education section, Mac Attack weekly tips and tricks for your Mac in the Technology section, or The Naked Scientists’ plain-English answers to your science questions in the Science & Medicine section.

5. YouTube

Sure, you can kill time—and brain cells—watching Britney Spears going down in flames at this year’s VMAs, or witness what happens when you mix Diet Coke and Mentos. But you can also find an introduction to calculus functions, Arabic language lessons, and a series on how to create fire effects in Photoshop. Rely on other viewers’ ratings to help you filter out the YouTube junk from the truly useful.

6. Education Index

The Education Index puts a huge database of educational websites at your fingertips. Simply click on a subject like archaeology, political science, or military technologies, and instantly get a list of links to sites both general and specialized that hold a wealth of information.

7. HowStuffWorks

From the light bulb to a rocket engine, HowStuffWorks breaks down how almost anything works with diagrams and easy-to-follow explanations. Don’t have an engineering streak in you? Check out “How the Batmobile Works,” “11 Stupid Legal Warnings,” or “What if everybody in the United States flushed the toilet at the same time?” No matter what you’re wondering, HowStuffWorks probably has an answer.

8. The History Channel

Surf through video galleries, timelines, maps, celebrated speeches, significant moments, and “This Day in History.” Enter in your birthday, and learn what’s happened throughout the years on the month and day you were born.

9. Dr. Math’s Math Forum

The Dr. Math forum answers thousands of common math questions, from elementary school to college level problems. Users submit their questions to the forum, and Dr. Math will post a response. If you’re having trouble in math class or with a problem set, it can help to read through old posts on the subject—chances are someone else has had the exact same problem you’re having.

10. Science

Not just for science geeks, the online version of the popular Science magazine offers thought-provoking and easy-to-read articles on everything from advances in neuroscience and astronomy to the latest in HIV research to “did you know” conversation starters, like why it makes evolutionary sense for certain animals to eat their young or why broccoli rubbed on your skin can help prevent sunburn damage.

11. Google News

Why pick and choose between news websites when you can harness the power and variety of all of them? Google News is a news aggregator that pulls all the top stories from thousands of news sites. You can use the power of Google search to find specific news items, browse standard categories like Health, Entertainment, and Top Stories, or personalize your Google News homepage and add custom categories of your own based on key words you choose.

12. www.chemistry.about.com

Articles, diagrams, walkthroughs and Q&As at About.com cover both the chemistry basics for new students and more specialized questions for more advanced students.

13. Education Arcade

Home to educational video and trivia games suited for middle school to college students, Education Arcade is entertainment that works your brain. In one of their augmented reality games, you can use GPS-enabled handheld computers to interview virtual characters and conduct large-scale environmental analysis to try to uncover the source of a simulated toxic spill.
