I am scheduled to take the cbest this Sat and have been using a variety of cbest books to brush up on my math skills. Using the practice tests in the Kaplan book or the Cliff's, I always get a decent passing grade of around 80% and some of those are just silly/stupid mistakes. However, when I use this REA (Research and Education Association) practice test book, I never pass! This one is so much more difficult than the others. The problems seem to be a big "step up" from the basic math in the others with at least 3 or 4 calculations for every problem. I am wondering what is closer to the actual test. Any opinions? I saw that Kaplan was recommended here but no mention of the other one. I guess I need another piece of chocolate but am getting nervous!
