After seeing some of these lectures and checking a couple of exams, I think MIT is actually not that difficult. The thing is they do have access to these awesome lectures and they're taught how to think. I'm positively sure that Calculus II and 18.06 are much more difficult in two universities I'm acquainted with than in MIT. However, they're taught how to think at MIT and most good universities just try to explore the limits of difficulty, rather than giving insights into thinking.####[['MIT', 'Other', 'POS']]
