I took the exam the first time after purchasing a different study program and failed. I was devastated! I really thought I knew all the material and would pass with flying colors since I had looked through several prep-material programs. It’s not that I didn’t know the material, the Therapist Development Center helps you understand how to study and what types of questions will be on the test. I am very thankful to Robin my coach. Due to not passing the first time, I was so nervous to take the test the 2nd time. Robin was so understanding and encouraging that I would pass after studying with TDC. Although I wanted to believe her I was a skeptic and emailed her questions up to the minute I was sitting in the parking lot of the test building. Thank you Robin for being so understanding and patient with me. You were right…I DID IT!!! I can’t thank Robin and Amanda enough for helping me get to the next step in my career. Hands down the BEST study material anyone can buy.
