This study guide is a joke. I purchased it primarily for the practice exams, expecting it to be similar in style to the exams included in the Microsoft Press Self-Paced study guides. Wrong on that count - the practice exams consist of 5 pre-selected sets of questions, 50 each. So much for semi-random ordering, or being able to do one massive 300 question practice test.
The amount of content contained in the guide is also pretty thin - roughly 1/3 to 1/2 the thickness of a typical Self-Paced guide. I was not impressed by the inclusion of third-party controls from Dundas and Telerik. This is supposed to be an ASP.NET exam, and in my opinion including third party controls is not relevant to "canon" ASP.NET.
My final and biggest problem with this product is the woeful proofing that was apparently done on the practice exam questions. A number of the questions are written with horribly incorrect English - my three year old has better grammar than whoever wrote the questions. An example:
"Which option from should you select to build the project after configuring a newly created web deployment project for a Web site?"
Secondly, I have encountered several questions that simply do not give enough information to even guess what the answer should be. It almost looks like they were expecting there to be some sort of sample code or configuration file sample to refer to, but that example never made it into the final product.
The worst problem with the sample tests is the inaccurate "correct" answers for some of the questions. This guide is purportedly put out by Microsoft, but they can't even seem to get the answers to their own test right. Doesn't exactly instill confidence in my exam preparation.
