This program has been SO helpful. I have had 2 children in the last two years and finding any extra time in my day to prepare for the exams has been incredibly difficult. I took the test the first time without much preparation (as I has just had my daughter) and I did not pass. It wasn't a surprise really, but it still was very disheartening. This time, I allowed 6 weeks to study (which is much easier to do when kids reaches over a year old) and I studied the program EXACTLY as the program requested. I am SO happy to say, I passed. After being out of the field for 3 years, the program completely prepared me for the exam, and I could not be happier with the level of customer service and encouragement I have gotten from TDC. Lastly, on a side note, Robin's voice is pretty perfect for the lectures, I just have to say. She didn't annoy me at all and I actually looked forward to study time! Haha. Truly! It was a pleasure to use this program.
