Who says you have to shell out top dollar or leave your home state in order to receive an Ivy-League caliber education? Thanks to the power of the Internet, dozens of colleges and universities from across the country have made it possible for students to download and view lectures from some of their top professors and courses.

The best thing about these online lecture sites? They’re free! Check out a few below:

And if you need to pump up on your math and science skills for upcoming SATs, make sure to check out the Khan Academy, which we first covered back last December. The founder, Salman Khan, is a Harvard MBA and has taped dozens upon dozens of YouTube videos detailing everything from the basics of algebra to the nitty-gritty of physics.
