What others are saying about LEED AP O+M Mock Exam …


“These are TOUGH sample tests. You need this book.!

“I used this book as a review in the day or two before my exam. The questions in this book could very well be found on the exam, but most actual exam questions will not be as complex as they are made here. Most of these questions on these mock exams have a twist or trick and many can only be answered if you know the materials backwards and forward. This makes for GREAT exam preparation because it makes you acutely aware of the types of tricks and the level of detail you MIGHT see on the exam…”

G. Patton


“I highly recommend this book!

“The book was extremely helpful for me passing the exam. The questions really challenged me to dig deeper into the details of each category. I felt this was one of several tools to help me be prepared for the exam. I highly recommend this book.”

Edwin F Sierra


“Such a great tool!

“I passed the exam at the first attempt. These mock exams helped me to learn how to tackle the problems and which areas I should focus on! I worked with another book of the author also. It took 2-3 weeks for my preparation.”
