Khan Academy is an online database of over 2600 video lessons in all different subjects. Need help in geometry? They’ve got it. Want to brush up on art history? Check. Studying for your SAT? No problem. Khan Academy is a non-profit organization that simply wants to help people learn. Founder Sal Khan has degrees from both MIT and Harvard, and he actually quit his job as a hedge fund manager to work on the Academy full time.
Though Khan’s teaching style may not work for everyone, there is enough information and variety in the lessons that it’s worth a look. The site’s specialties are math and science, with videos covering arithmetic, algebra, geometry, pre-calculus, calculus, statistics, biology, physics, chemistry, computer science, astronomy, and more. In addition to the videos, there is also a math practice section where you can work your way up from simple addition to complex calculus problems.
There are many more subjects, however: some overviews of U.S. history, a lot of banking and finance-related lessons (due to Khan’s experience in that field), some videos for specialized tests or curricula (such as the SAT), and a huge collection of art history lessons made by guest teachers. The collection of videos is truly astounding, so whether you need homework help or you are just curious about a certain topic, there is a good chance it’s there. And if not, it may be coming up soon!
Khan Academy is a great website for students, but strangely, it’s a bit of a secret. I can’t help but wonder why I didn’t hear about it until now, in my senior year of high school—it would’ve been so helpful just a few years ago! Don’t be afraid to try it for yourself and get the word out about this amazing resource.
