Query: waste of money

I would not recommend this book as a resource to prepare for the CST...It definately had MANY errors and also poor organization of material. There was not one graph, chart, timeline or graphic organizer to enhance presentation of material. I also found that the material presented in the book was not true to the material covered on the actual test. A friend had used an online resource and her materials were much more accurate of determining test material.
