Are there any good online Math colleges? I know that online education has been booming for a while now, but I've been trying to find an online college that gives **Pure Mathematics** courses.

It's mostly for self gratification as I've always loved Math and the various challenges it presents, but with the scarce time I have, I'd like to take things at my tempo, by doing things when I can.

The best choice would obviously be a free online college, but I'd have no problem with paying a decent fee if I had to, in order to access the courses.
