Query: Save your money

This has to be one of the worst books that I have read that is supposed to prepare you for the test. Granted, if you are persuing any of the tests listed in this book, you should have in-depth hands on. However, one would think that any book that claims to give you a healthy view of the test would cover the test material. This book, in my opinion, greatly missed the mark on the important topics. Save your money and by a book that will prepare you for the real test.
