Query: This is THE BEST AP Chem review available!

This book has a great summary of each class topic, including all terms and concepts required on the exam. Everything is well-organized, and easy to understand. It has examples of each type of question, with explanations, at the end of each section. In addition, a full-length exam is given in the back. Everything anyone taking the Advanced Placement Chemistry exam needs is included. This review is much better than other review books available. This book helped me recieve my "5" in 1998.
