To start let me just say I took and passed the Law and Ethics test with only using the TDC study material. I enjoyed this study material. I was originally skeptical because the material is mostly auditory. In the past I have primarily learned by reading, but I had heard such good things about the program so I thought I would try it out. I found that the information was extremely useful and relevant to the test. I was able to take the auditory information and take good notes and further break down the information into note cards. Ultimately that was all I needed to do to pass. The information given was sufficient and I was able to make it work for me. Also I loved the study tests. Some of the questions on the test were almost word for word from the practice tests. They were extremely useful because they were timed and the same number of questions as the test. I found it extremely useful to practice under the same conditions as the actual test. Overall I found the study material to be effective and very much worth it.
