Good. I took it for the October 2016 exam and passed first try. They give you all the reference material you need. Conceptual questions on the pe exam are where you will have to pull from your experience...and there were a lot of conceptual questions.
The breadth review helped me the most. I used mostly my Das textbooks for the depth exam, but the binder they give has all the same information. I was just familiar with the layout of my textbooks.
