I passed it this week by over 30 points using 2004 & 2006 practice exams, second hand CD set, and a current study guide put out by an individual not affiliated with a company. I had familiarity with DSM 5 through teaching undergrad psych classes as well as simply going through youtube clips and the DSM itself. I previously had invested (almost 2k!!) in an online program, followed it exactly as directed, and failed the test. I will tell you why. The practice tests from that company were in no way reflective of the actual EPPP. They were much easier and contained more definitional items as opposed to applying concepts. Using the old practice exams (no idea who made them- maybe AATBS or Academic Review), and taking the PEPPO - I knew I could pass the EPPP. My practice test scores (all 14 of them!) averaged out to 74% and my PEPPO score was 10 points lower than my actual EPPP score. That was the long answer. The concise answer: if you have 2011 materials you should be fine. In my opinion, the most valuable study tool for me was taking practice exams and an inexpensive online app.
