You need to answer about 60% of the questions correctly to pass the LEED AP Exam. There are a number of books that you can use to prepare for LEED AP Exam:
1. USGBC Reference Guide. Since you need to pass at least one of the three LEED Exams (LEED-NC, LEED-CI, LEED-EB) to become a LEED AP, you first need to decide which one of the 3 exams you want to take. You need to select the correct version of the Reference Guide for your exam. Most people tend to take LEED-NC exam to become LEED AP.
The USGBC Reference Guide is comprehensive, but it gives too much information (about 400 over-size pages). A lot of the calculations in the book are too detailed for the exam. It is also expensive (about $200.00 each, most people will not buy it for personal use, and will share an office copy instead).
It is good to read the reference guide from cover to cover if you have the time. The problem is not too many people have time to read the whole reference guide. Even if you do read the whole guide, you may not remember the important issues to pass the LEED AP exam anyway. You need to repeat your reading several times before you can remember any study materials.
Reading the reference guide from cover to cover without a guidebook is the most difficult and inefficient way of preparing LEED AP Exam, because you do NOT know what USGBC and GBCI is looking for in the exam.
2. The USGBC workshops and related handouts are concise, but they do not cover extra credits (exemplary performance). The workshops are expensive, costing hundreds of dollars each.
3. Various books published by third party and available on Amazon. Most of them are not very helpful.
There are many books on LEED, but there is not a really good one until now.
"LEED AP Exam Guide" will fill in the blanks and become your reliable source:
a. It gives you more information for your money. It has more information than the USGBC workshops.
b. It is exam-oriented and more effective than the USGBC reference guide.
c. It is better than most if not all of the other third party books. It gives you study materials, sample questions and answers, mock exam and answers, and critical information on building LEED certification (LEED-NC) and going green. Other third party books only give you a fraction of the information.
d. It is comprehensive yet concise. It is small and easy to carry around. You can read it whenever you have a few extra minutes.
e. It is a great timesaver. I have highlighted the important information that you need to understand and MEMORIZE. I also make some acronyms and short sentence to help you easily remember the credit names.
It should take you about one or two weeks of full time study to pass the LEED AP exam. I have met people spent 40 hours to study and pass.
You may notice the book cover image for "LEED AP Exam Guide" has not shown up on Amazon yet. It takes some time (sometimes several weeks) for the cover image to show up at Amazon's book listing system, even though it was submitted earlier.
Don't worry, if you order "LEED AP Exam Guide" from Amazon now, the book itself does come as a complete book with nice front and back cover.
I also uploaded the book's cover as a customer image under this book listing at Amazon. If you click on the link "See all 2 customer images" on the upper left hand corner of the book's Amazon web page, you can see it.
