    I purchased this study guide and read a chapter a day for 3 months. I put the book down for the entire 2 weeks before I took my certification test. I scored a 92%. This book is all the material that the test had on it. There are no used books available. I looked! This is a great book Plenty of exercises and sample test questions (I noticed several were on the test!)
