I recently took the CBEST test on Feb. 07, 2009, and I just got an email for my unofficial scores today (02/23/09), and I passed! This book really helped me understand how to solve the different types of problems, and where to start when writing the essays for the test. There were probably only a couple of problems on the actual CBEST test that I did not know at all. This book was very helpful. I just wish this author wrote one for the CSET test. =)
