I think RMP is more for undergrads who want to coast through their degree with the least amount of effort.
RMP is also very useful if you want to sign-up for classes taught by attractive professors. I like to have something nice to look at while not doing course-work, lol!
I agree with you, I was just trying to help magfrump.
There is, of course, Kahn Academy for fundamentals. We have already had a discussion on How to learn math.
What resources exist detailing which mathematics to learn in what order? What resources exist that explain the utility of different mathematical subfields for the purpose of directing studies?
