Passyourclass is a website that sells individual CLEP study guides for $35 each. They come in PDF documents but I think for a few dollars more they are mailed.

I bought their US HISTORY 1 guide. The test questions were bad...horrible. It was a useless practice test. In fact, even using their own material you wouldn't be able to answer the practice exam. The content though (It's like 50 small pages) helped me out a lot though. Was it worth the money? Nope. But I haven't taken a look at College Algebra.

InstantCert doesn't have any flashcards for CollegeAlgebra, only Mathematics.
