I signed up for AATBS the first time and my friends had signed up with TDC. I did not feel prepared at all for the exam when I took it the first time. My friends who used TDC passed their test without a problem. When I called AATBS to let them know I didn't pass it (as they had a pass guarantee) they did not offer to help me except to say they added another exam on their program. Their testing material was not sufficient at all compared to TDC. I was depressed after the test and decided to pay for TDC's program due to my friends success stories. I want to say that though I was nervous going into the exam, I felt prepared. I took Amanda's words of affirmation in the test with me which helped to calm me. I finished the test early and though I felt good about the test but it took PSI and BBS 9 weeks to get me back my results. They were 9 long weeks! I also want to thank the staff at TDC for understanding and keeping my test bank open for another month due to me being sick and having several things happening in my life that caused me to have to reschedule my test. I highly recommend TDC to everyone I talk to who is going through this process. THANK YOU SO MUCH FOR YOUR HELP, ASSISTANCE AND UNDERSTANDING OF WHAT THIS PROCESS IS LIKE FOR MFTI'S! :)
