I'm in a similar boat to you (although I'm technically relearning stuff I vaguely knew in college), and my solution has been to check out several of the books mentioned over in the "Good 3D Math Theory BooksGood 3D Math Theory Books" question here. If you're a book learner that may be a good way to go for you. Especially if your college doesn't actually have a good 3d graphics course (mine didn't).
