Is there any good sources online to learn college algebra?

I am kind of cheap, I want to learn college algebra and try to test out of it, for my degree. I know this is hard to believe I've been in college/ university for several years. And I have never had to take it, I've always taken industrial math or other types of math. I'm one of those guys whose changed majors a lot. From the schools i have checked, the course is around 3 to 5 hundred. I go to a private school now and I am not willing to pay there prices for this course. So is there any good cd-roms? or online sources I can learn this from? I am also willing to buy or pay anything within reason. A side not I need this more as a refresher than to learn it
