I took the Masters exam on June 4, 2016. I ordered the study guide and the DSM 5 diagnostic book. I studied the guide for roughly 6 weeks prior to taking the exam and passed more than 10 points above the score I was required to get in order to pass. The material is easy to follow, read, and comprehend. The material is organized in a logical way that flows nicely as you are studying through the book. For me, it made it like reading one giant social work textbook that held all the important/significant information from my classes at my fingertips. I still look through the book and use the DSM 5 book in practice. I’m preparing now to take the Clinical exam and plan on buying the updated materials. Good luck!
