This book does the one thing I needed most: it was a quick reference that covered all the test topics in just enough detail, and nothing more, and the two practice tests are of striking similarity to a real test (the tests on the CD, however, are considerably more difficult than the real test - I failed these and still did great on the real test).
When I opened the book I was only strongly familiar with the C# language proper, the form designer, and some basic controls; when I finished, 2 days later, I had memorized all the necessary little details for a dozen topics I knew nothing about before, including nearly all of ADO.NET. I think I would have failed the exam before reading it, but after reading it I beat the pass mark by a wide margin. One piece of advice: if you're after an MCAD, go ahead and pick up Exam Cram for 70-320, the next exam, and read Chapter 1 to get more important details on ADO.NET.
Now the bad. This book is great for passing the exam in a hurry, but you don't get the in-depth knowledge of and familiarity with the topics you get from hands-on experience. It is true to its name, an exam cram guide, covering only the specific details essential for the exam. I was also displeased that it contained a large number of typographical errors, misspellings, and, worse still, misleadingly used circles where boxes were intended for some questions in the second practice exam. It also made some recommendations of questionable accuracy.
Nevertheless, I highly recommend this book to anyone looking solely to pass the exam in a hurry.
