I would just like to say that this program is a critical piece in passing this exam. The test is not easy even for the most seasoned clinician. Throughout the exam the tips shared in the program ran through my mind and helped me get through this fast paced exam. There is no time to linger on questions and you have to keep moving. Without the knowledge gained from the TDC program it would've been nearly impossible to pass. I now can say that if you study hard, complete the ENTIRE program, and with a little luck, this program really does have a 99% passing rate. My fellow colleagues who used other programs did not pass, but everyone I know who used TDC did. I highly recommend it!
