Current AP O+M Exam Version is V4
The exam contains 100 questions, and you are given two hours to complete it. A passing score is 170 or higher. At the end of the exam, you will learn your score. If successful, you will be awarded your LEED AP O+M certification.

If you run into a particularly hard question on the O+M Exam, do not panic. Simply skip the question and come back to it at a later point. Some questions during the rest of the exam may "jog" your memory. For each question, you have more than ample amount of time to complete the question. Always spend some time reviewing your AP Exam to make sure you have answered every question.
