Query: Don't buy this book!

I have taken three Cisco exams so far and two of them were with Syngress books and one was with a Cisco Press book. I thought I learned my lesson when the first book was bad but I didn't. I learned it again wit this book. The Syngress books do NOT cover all the sections on the exam, not the way the Cisco Press book did. This book also had me reviewing material that was not even remotely on the test. I will NEVER but a Syngress study tool again.
