I was so nervous going in to take the exam only to find that I was well prepared and capable of passing. It was as if TDC had given me all the right answers although they were not the same questions. Only one question threw me off. Otherwise TDC covered the questions and answers thoroughly. I am now preparing for the next exam in CA and wholeheartedly hope that TDC can help me prepare for that exam as well. Thank you for creating a system that seems fail proof.
