You don't need to go to Cambridge to enjoy all the fun of a wildly expensive education.

There isn’t much that you can’t learn for free on the internet, but it’s not just YouTube tutorials — if you know where to look you can actually get something approximating a world-class education without leaving your bedroom.

The Massachusetts Institute of Technology is a global leader on open-access education. The school has posted material online from 2,260 different courses, which means that a motivated learner with laptop and a good internet connection could become an expert in just about anything, and skip the $44,720 in annual tuition. As a bonus, exams and assignments are optional.

Of course, with so many subjects to choose from, it’s hard to know where to start. We’re here to help. Here are some introductory-level courses, including video lectures, that you’ll probably want to get started on today.
