UCCS Video Course archive has nearly complete coverage of in-major math courses, and a little poking around on professor web pages will usually get you course materials to go with them.
UCCS is apparently world-renowned for their freely-available online video math courses shot in PanOpto 2-perspective view, so you can see the boardwork and the notes at the same time.
