Although I had the normal test jitters going into the exam, I felt so confident once I started the test because the questions mirrored the TDC's content and mock exams so closely that I felt as though I KNEW the information. They made studying easy and manageable - I followed the sample calendar and took 5 weeks from start to finish to study for the Law and Ethics exam, which felt just right. I would HIGHLY recommend TDC to any Social Worker - well worth the money.
