Query: Disappointing

I have used the New Riders MCSE study guides all the way through my MCSE study preparation, usually in conjunction with the Coriolis Exam Cram series. I found this book to be very light on technical content, and to contain several errors. This is very annoying and confusing when you do not know enough about a subject to be sure that you have just discovered an error. I am currently looking for additional study material for exam 70-219 as I do not feel confident after reading this book. This is a good general introduction to AD design, but look elsewhere for substance. The Exam Gear test questions do not seem anywhere near as challenging as the Microsoft Test PEP questions that I have purchased, which leads me to further doubt the content of this book.
