This book is riddled with typos and incorrect answers. As I read the book, I got so bothered by all the mistakes that I marked them all in red pen and am considering sending it back to the publisher (I think they should pay me for serving as the editor!). Although it did help in my prepartion by making me familiar with the format and general content of the CBEST, there have to be better books out there. Along with all the typos, there were areas, particularly in the reading section, that were not even discussed in the book. Just a tip: take the practice test on the CBEST site along with your other test prep just so you aren't caught off guard.
