Is there any undergraduate mathematics learning website like edx or coursera?

Question

I want to take courses in mathematics of undergraduate level. But in edx or coursera they have only few undergrad math courses( only calculus or a little bit of algebra). There are no hardcore maths courses like group theory, ring theory etc. Is there any site where I can get these?

Thanks!

Answer 1

Take a look at MIT open courseware http://ocw.mit.edu/courses/mathematics/

Answer 2

I don't know of any website that collects these all in one place, in the way that edX or Coursera.

But most Ivy League universities offer at least free lecture videos, sometimes the problem sets and tests too, if you look around. For instance, here's one course on Abstract Algebra, from Harvard.
