As we all know, NCEES structures the PE into two exams: AM and PM which it identifies as “breadth” and “depth” respectively. Each exam has 40 questions. Each lasts 4 hours. The only difference is that the AM exam has 5 disciplines and the PM exam has one. This means that both breadth and depth problems are designed to fit into an exam structure that allows about 6 minutes each. However, the PM exam has 4 to 5 times as many questions drawn from one discipline compared to about one fifth of those which are represented in the AM exam. So, we could call the PM exam “breadth” because there are so many more questions!
This is why we at PeReview.net don’t differentiate between breadth and depth problems. Instead,we advocate breadth in preparation which, in turn, will deliver depth.
