Poorly written study guide for CSET social studies preparation. The book has numerous grammatical, spelling, and factual errors. There are no California specific historical questions that you would expect to find in a study guide oriented towards a CSET test for California. Instead you will find several questions oriented towards Florida. I agree with other reviewers that I could probably write a better book myself. Disappointing, especially in view of the price. My recommendation: buy Advanced Placement guides in individual topic areas such as World History, U.S. History, Economics, etc.
