The Total CISSP Exam Prep Book is not a well constructed book for the purposes of studying for the CISSP exam. It lacks theory, it just provides questions and answers, with the answers right in sight of the questions. Also, are the questions even relevant for the current exam, if so then there lies a flaw within the CISSP certification process with so much of the emphasis placed on the rote memorization of test material. So even if you want to just practice by answering the questions, the answers placed where they are makes it too easy for your eyes to stray to the answers.If I would have paid the suggested retail price for this book I would have felt really, really disappointed, as it was paying a fourth of that cost I still am really disappointed.
