Just took the test in October. Results came back first week of December.
My thoughts on the test...
Not an easy test at all. I would recommend taking it after a clinical residency. Pretty intimidating, almost all of the people I knew that took the test were residency trained clinical pharmacists, clinical pharmacists that has worked 5+ years, or professors at pharmacy schools.
Stats/QI/hospital admin questions were 20% of the test
Clinical Acute Care was 40%
Clinical Outpatient Care was 40%
Min pass was 121. Average was 132. Range was 49-187. Std Dev 23.
Assuming normal bell curve, probably 66% passing rate.
I believe people who work in a hospital clinical environment have the advantage. I had to relearn a good part of the IP subjects (ID, AC, fluids & elec, Onc - supportive care, IM, CC). Spent 2 months studying for the test which gave me enough time to thoroughly read the prep books twice.
Would not recommend the PSAP books. It's overkill and I feel that most of the questions that are on the test were in the book. If you study from the prep book real well, it's enough to pass. If you want to kick ass, then you're practice experience and other studying material will give you the edge.
I ended up target studying topics that I felt were my weakest.
As for the benefit of the test,...it's another 4 letters after you name which gives you a benefit against another candidate (assuming everything else is the same).
What are your recommendations for someone taking it next year? I heard there used to be quite a bit of stats on it, but I haven't talked to anyone who's taken it in the last few years. 
I definitely wouldn't get the lectures without the prep books, I think they would be hard to follow.
