Has anyone ever heard of The Kahn Academy? My philosophy professor turned me onto it the other day, though it has nothing to do with philosophy, it’s worth a look. It’s basically a learning center for Math, Sciences, History, and other Institutions. . . there’s videos, posts, tests and quizzes, and whole lot of other things. And best part is, it is changing perpetually!
