I'm trying to teach myself college algebra and precalculus. What's the quickest / most efficient way to do this?
I took Algebra I & II a long time ago, but I don't remember most of it. Recently I've reviewed Algebra I and a lot of Algebra II, and now I'm up to the more advanced parts of Algebra II.
I need a resource that's self-paced (I don't want to be tied down to a slow teaching schedule) and as quick and efficient as I can get, but it needs to be comprehensive. I also need some way of testing myself to make sure I understand and remember the concepts.
So far I've tried a some of the Cliffs Quick Review series and Khan Academy. They're both quick and self-paced, but I'm concerned they're not comprehensive enough. Also, Cliffs doesn't have much self-testing, and Khan Academy lacks quizzes on many topics.
