Norman Hall's Corrections Officer Exam Preparation Book

I love this book. It's difficult, it gives advice on how to solve the various problems you will face when taking the CO exam, and it basically has 2 practice exams within the entire book. It also covers the different exams you will face during the hiring process such as the physical exam, oral board review, psychological exam, and how to prepare for those. Though there is not sufficient data on what to be prepared for during the psychological exam, the book's main focus is on the written CO exam. The author tells you how best to solve the various problems and along with an answer sheet, he shows you how to properly work out the problem in case you missed the correct answer.
