LCSW
I've taken this exam twice before. Once with another prep course that costs a mint, offers workshops, tons of written material, multiple mock exams, etc. I failed so I tried TDC, liked it, but failed again. The difference was the other prep company wanted another large chunk of money before I could study with them further. TDC willingly offered their study materials and support free of charge. They stand by their claim to be with you until you pass. The material is streamline, succinct, and does not overwhelm. In my opinion, TDC offers exactly what is needed to pass the exam. Second time around with TDC I studied for 4 weeks after taking 11 months off and passed.
