Query: MySQL Certified because of this book

I studied for the MySQL DBA exam using this book, chapters 23-42. I passed both exams on the first try two weeks apart. I can truthfully say that in order to pass both exams, you must know certain facts from several different chapters to answer a single question. This is especially true for mutiple choice questions that require multiple answers. While there are many typos and changes to MySQL since the books release, just go to the URL http://www.mysql.com/certification/studyguides/errata50.html and make those corrections, and you will find that this book is indeed a complete study guide. The developer chapters (1-22) are just as replete with needed info. Have fun studying the book and passing the exams.
