Query: Don't waste your time.

I found this book not to be very useful. The questions were not even close to being like the Microsoft exam questions and some of there answers were completely wrong. When I bought this book I figured that it would help me prepare for the exam. It didn't. I didn't expect the questions to be like microsofts but they should have been better than this. It also didn't map very well to exam 70-176. It was designed for 70-175 and from what I have heard about this exam this book would prove useless. Save you money and purchase another product.
