I see you took the NPTE in April but I feel this may benefit others who prepare for future exams.
PEAT 1: 81% (scale 655)
PEAT 2: 81% (scale 715)
O'Sullivan 2015 edition 1, 2, 3: 67%, 71%, 73%
Score builders 2012 edition 1, 2, 3: 74.5%, 74.5%, 74%
Passed the NPTE first try. I did take the Scorebuilder's review course as it was offered through my program (took it in November, but didn't take the exam until April); I did find it beneficial for introduction into how to study but I ended up not following any of their advice as far as CATs and content outline (being able to verbalize all of the information). I know people that have taken both TherapyEd & Scorebuilders review course and they found TherapyEd was better.
What worked best for me was taking practice exams and studying the wrong answers, making study guides with information and reviewing it frequently. I studied for 7 weeks, 3-4 hours, 5 days per week and took weekends off.
I did find that my preparation paid off but mostly in that I was able to deduce correct answers based on how they were worded. During the exam, I did feel that I hadn't studied a majority of the material that was on the exam, however, I walked away feeling like I couldn't have prepared any differently for it.
