It was extremely misleading for the author to list questions from exam P as if they were representative of the exams at a large. I'm an actuary, and I passed that exam with a 10 (maximum grade), with a nights review of my probability class notes. Then I failed my next exam twice. The first couple exams are very simple, and then it ramps up considerably. As others have mentioned, the hard part of these exams is not the individual material, which is never far beyond undergrad level, but the sheer quantity of it. It's also very unmotivated in some cases, so it's hard to piece together a full picture of the material that you're trying to learn.
