MIT began putting courses online in 2001; more than 1,500 are already available, and all of its 1,800 courses should be posted by the end of this year.
So far, the most popular online course has been an introduction to electrical engineering, Margulies said, but visitors to the site can also school themselves on such subjects as cell-matrix mechanics, holographic imaging, hip-hop, and How to Make (Almost) Anything.
Some of the classes include video, interactive features, and practice exams.
Of course, if you want a degree, you’ll still have to move to Cambridge and pay the hefty tuition fees.
And then there’s the matter of actually having the qualifications to be admitted.
