This book had a limited number of practice questions, but what really made me nuts was the amount of time the authors spent telling you what is false. They included information in every chapter about common misconceptions, but they didn't always word it so it was immediately plain the information was wrong. Those who study the mechanics of learning and test taking will tell you NOT to add in the wrong information, it just clouds the subject. Yes, I passed the test, but I was very frustrated trying to use this book to learn the right answers.
