I felt the TDC material for the California Clinical exam was completely on target. The information was sharp, organized, and to the point, thus I could easily retain and recall it. Combined with the strategies for reasoning and test taking I was able to reason my way through questions that seemed weird or when none of the answer choices were a good fit. I had gone through all the material and I reviewed the Top 50 topics a few days before taking the exam and I felt that it covered exactly what was on the test. While taking the actual exam I used the techniques Amanda taught and I passed. I am very grateful. I am so glad friends/colleagues recommended TDC.
