Query: Excellent in depth info .... average test prep

I just passed the test using this book for preperation. While it gives an excellent, in-depth overview of Photoshop, it falls a little short in actually preparing you for the test. I would highly recommend this book as a review before your test, but don't count on it giving you all the answers. Experience is the best study guide.
