Why go to college if you don’t even have to any more? The world-renowned MIT has put its entire class catalog online under the moniker MIT OpenCourseWare. Sure you won’t get professorial feedback or fire-under-your-ass lighting, but the information’s there.

It’s foolish to assume that you’ll be able to teach yourself enough material to earn a degree, but we’re suggesting that you double-check your notes in a crunch. If your own professor doesn’t put his or her notes online, then you might be able to find some overlap in the MIT OpenCourseWare catalog. And I don’t care which school you go to, MIT probably knows better.
