TDC made the material so plain for me which helped me pass the exam on the first attempt! I really appreciated the audio, as I was able to take the instructors voice in the exam with me. I'm a very visual learner and the format of the study materials definitely spoke to my learning style. I work full time and I have a lot of extracurricular activities on my plate, so the study plan was very helpful to my time management. Hands down, I would recommend this system to anyone looking to study for any of the major licensing exams!
