If you're getting ready to take the COOP or HSTP exams this is a great book to study. It has detailed information and strategys for all the parts of the exams which will help you alot. It has two sample exams for the COOP and HSTP with detailed explanations for each answer (but after I took the HSTP I found that the sample exams were much harder than the real thing). Another good thing about this book is that it doesn't have too many mistakes, like some other of these books, making it very easy to understand.

Although this book is very educational in some areas, it lacks difficulty in others. This book has helped my cousins, sisters, and mom. Overall, I'd say that thi sbook is well-written and has helped many people.
