TDC is legit. I was ready to throw in the towel after failing twice using other study materials. I began to question my career and doubted my abilities to continue. Lot's of demons to deal with, but then I heard of TDC and immediately began to notice the rationales and the logic behind taking the Law and Ethics. Everything made so much sense. I walked into the test site focused and attacked the test. I did not allow the test any wiggle room. Now I'm coming for the clinical test! Thank you all at TDC.
