Well, I don't know how you can get in besides working really hard, but you should go to http://ocw.mit.edu/index.html
I saw this link on a freebies thing. It's called opencourseware and it's "a free and open educational resource (OER) for educators, students, and self-learners around the world." It's a publication of MIT course materials
PS For all you college students, some of this stuff might help you
