I just took the child board exam and this question-and-answer book actually helped a lot. The exam takes three days: half of one for the written exam, a 75 minute preschool/school age oral exam, and a 60 minute live adolescent oral exam. This book helps the most with the written exam. The questions are similar to the type on the real exam. Hendren provides questions in either multiple choice or K-type format, with some matching questions. These are followed by answers and brief explanations. The explanations are usually helpful, but there are some that are confusing or skimpy. I actually got frustrated with a few of them. The material is a little dated (little on atypicals and a lot on tricyclics). But overall you will learn a lot and be in full "question mode" during the exam. There are a couple sections at the end of the book to help prepare for the oral exams. The preschool/school age one is more pertinent, because there is a written vignette on the actual exam. Overall, this book is well worth the investment!
