Review: DO NOT BUY - I just took the LEED AP exam this morning, and I'll stress again what another reviewer has already mentioned, that clearly this book was not edited at all. The quiz keys in the back of the book don't match up with the questions. For example, the answer key will say that for question 3.4, the answer is choice C and will give an explanation as to why. However, the explanation will be entirely unrelated to the question, and the 'clarification' won't make sense. It's almost like someone filed the questions and answers out of order, which is really detrimental for studying. Did the author just forget to have this edited?? I'm just floored that there are such serious and glaring errors in an exam prep book. There are also some questionable discrepancies in the information from the O&M Reference guide published by USGBC, such as water baseline calculations. This book states that the baseline should be based on fixtures installed after 1993, using 120% and 160% reductions from baseline depending on installation date. The USGBC Reference Guide uses 1995 as the reference year, and reductions of 120% and 150%. It makes me seriously question what else is incorrect in this study guide. The most useful part of this book is the inclusion of study worksheets, which are one worksheet per credit, and appendixes that detail the synergies and references per credit. HOWEVER - they are not specific enough to help you pass the exam. Do not buy this book, if it's the only thing you use you will not pass the exam. Save your money. The only helpful study guides I found out there were with GBES, it's more money and predominantly online but their practice tests actually represented what I saw on the real exam. And I'm not being paid by GBES so not trying to plug a product. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #5,607,506 in Books ( See Top 100 in Books ) #3,627 in Architectural Drafting & Presentation #3,741 in Architecture (Books) | | Customer Reviews | 3.2 3.2 out of 5 stars (11) | | Dimensions | 8.5 x 0.9 x 10.9 inches | | Edition | 1st | | ISBN-10 | 0470608307 | | ISBN-13 | 978-0470608302 | | Item Weight | 1.96 pounds | | Language | English | | Print length | 336 pages | | Publication date | September 13, 2011 | | Publisher | Wiley | ## Images ![Guide to the LEED AP Operations and Maintenance (O+M) Exam - Image 1](https://m.media-amazon.com/images/I/31Sk0ZkS09L.jpg) ![Guide to the LEED AP Operations and Maintenance (O+M) Exam - Image 2](https://m.media-amazon.com/images/I/416y+hi1ljL.jpg) ![Guide to the LEED AP Operations and Maintenance (O+M) Exam - Image 3](https://m.media-amazon.com/images/I/51mABH3pgkL.jpg) ![Guide to the LEED AP Operations and Maintenance (O+M) Exam - Image 4](https://m.media-amazon.com/images/I/71XCg5DJBCL.jpg) ## Customer Reviews ### ⭐⭐⭐ Three Stars *by I***R on March 16, 2015* The book is great, the problem is Amazon's reading application, it is horrible. ### ⭐ DO NOT BUY *by E***9 on June 22, 2015* I just took the LEED AP exam this morning, and I'll stress again what another reviewer has already mentioned, that clearly this book was not edited at all.

The study work sheet are well written, and although a couple of typos are present, the meaning is obvious, and doesn't outweigh what makes this a 5 star book.With various types...check all that apply, fill in the blank, best answer, etc. The answer key helpfully describes why the correct answer is correct, and why the incorrect answers are not. At the same cost of other LEED exam guides, this is a must buy if you want to pass O+M exam the first time you take it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/11337102-guide-to-the-leed-ap-operations-and-maintenance-o-m](https://www.desertcart.co.th/products/11337102-guide-to-the-leed-ap-operations-and-maintenance-o-m) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-26*
