A background on my personal experience: I'm a LEED AP O+M and have experience preparing LEED EB O+M submission packages for over 10 buildings, so when I went to review this guide, I was terribly unimpressed with the level of carelessness and typographical errors in the mock exams. This book was clearly written as a way to make a quick buck off of the LEED system.
Some of the many issues are:
1) Several questions are duplicated, so there aren't even 200 unique questions in this guide
2) The answer key is incorrect. The questions are multiple choice, so when the answer key is wrong, it literally points you at the wrong answer and tells you it's the right one.
3) Typos throughout the book, which is extremely bad for a LEED exam, where the exact terminology is very important.
4) Several questions don't even make any sense. Taking this exam, I left many answers blank because I just had no idea what the question was even asking.
5) The "Solutions for difficult questions" aren't solutions; rather, they simply refer the reader to sections of the reference guide where they can find the correct answer.
In conclusion, would not recommend to anyone serious about getting their LEED AP O+M.
