Query: Best study guide for the certification exam

I studied this book two weeks and passed the test easily. I think it is the best study guide that you can find in the market. I strongly recommend this book to programmers who are willing to write the test. The material necessary for the test is clearly and precisely discussed and presented throughout the modules. The only thing that I would like to criticize is the practice test on the CD-ROM which is the repeating of test questions found at the end of each chapter. I could not find any reason for that.
