TDC is a terrific study program and very easy to follow. I went through the process only once and felt very prepared. Amanda's recorded rationales were the perfect learning tool for me and it helped tremendously to bring her voice into the test room, just like she recommended. It was calming to imagine her saying, 'would A be an appropriate answer? Absolutely,' or her resounding, 'No!'s.' Like Amanda suggested, I 'tolerated uncertainty' trusting that staying calm going from question to question reading every word of each stem and every word of the answers would take me to a PASS!
