Like most CHT exam candidates, I was so overwhelmed when I started to study. I really didn’t know where to start, but the Purple Review book allowed me to make a schedule that I was able to follow, and made sure I wasn’t missing important topics. The most valuable part of the Purple book is the explanations and the helpful hints between the questions.

I also purchased 5 practice tests from There is nothing that prepares you for a sit down examination more than blocking your schedule for a few hours and making yourself take an exam. The tests were very similar to the actual exam, and it also helped me to review what topics I needed to study more.

There were a few instances where I had questions or needed clarification, and Susan was so responsive to my emails, it was like talking to a coworker! I highly recommend any of the material from if you are preparing for the CHT exam.
