If you're going to be taking a number of CLEPs, a good investment is The Official CLEP Study Guide book of practice tests. It has a practice test for every CLEP and I found it to be very reliable. If I got over half the questions right on the practice test, I passed the real thing. I usually tried to be good enough to get 2/3 or 3/4 of the questions right to give myself a buffer. I always scored in the 60s or higher on my CLEPs.
