Query: Not too helpful

This book has good graphs and short descriptions, especially if you're looking for the quick definition of an economics term, but overall, it is too general and not helpful enough when you are studying for the AP Economics exam. I used it to review, but the book did not go into enough detail to really be of use to me. Also, there were many instances where the notes in the CliffsAP book contradicted with what I had learned in my economics course and in various impressive, reliable textbooks.I do not recommend using this book. It was quite a waste. I have heard that "5 Steps to a 5 on the AP exam" is better.
