Query: Save your money

I bought this book to prepare for the NBCOT exam, and found it to be pretty much useless. The questions are not formatted or in anyway similar to those on the exam, and the answers in the back are very brief, one or two sentances,and don't offer much clarification or explanation regarding correct or incorrect answers. I found that most of the book focuses on terminology or basic concepts; not at all as in depth or as situational as the real exam.
