I went into the exam feeling good about my studies with the practice tests and lectures. What a great relief when I looked at the questions and they were almost exactly what I had studied as far as concepts and rationales for the responses! I have had the support and encouragement of the TDC team from the very start of my study program. I was able to send questions to them and get immediate responses. I invested the cost in the beginning for the program, and have not had to spent a single penny past that for all the support, resources, materials, and extensions I needed. It was WELL worth the investment for me. I spoke with a couple of my friends who used other study programs, and they shared that when they took the exam, there were large chunks of material that their programs had not covered, which caused them to have to guess at the answers. I have been telling my friends to consider making the investment to use TDC because of the guarantee $$, the constant and immediate support and feedback, the simplicity of the study materials and practice exams, and just the overall feeling of the program. I don't need a lot of in person lecture time. I do better with a program like TDC. Check it out!
