There are better sources out there. Check out MIT OCW or Online Yale Courses. MIT OCW is the best, IMO, but the Yale one is pretty good as well. I taught myself calc 1-4 through MIT OCW while in HS. Got a 5 on the AP Exam, then proceeded to get As in all of my college classes while only attending for tests. It's great shit.

OCW has been around for a while now.
