Reddit reviews CLEP® Chemistry Book + Online (CLEP Test Preparation)

See if you can't buy/check out the REA Chemistry CLEP book for a refresher. I bought the three books for my three exams, read through each and took the two included practice exams, and passed all three of my CLEPs on the first go with just two days studying for each. Had been more than 10 years since I had taken a history class (and I never even took Psych!). Easier subjects than chem though, of course.
