I took Testmasters and improved from 149 to 173. However, my method of preparation wasn't just the Testmasters course. I took the course and received all of the books in the summer of 2003 and I attended about 2/3 of the class when I became disheartened with my low diagnostic scores (I went from a 149 to 159. I didn't even bother taking the 3rd diag). Exacerbating the situation was the fact that my Testmasters instructor, who was excellent by the way, had photographic memory and completed all of the games perfectly in his head without writing down a thing. Then, this summer, I decided to study for them again and I went through all of the Testmasters books and bought some of the recent preptests to use as diags. Unfortunately, my October exam didn't go to well and I cancelled my score. After that, I bought the 3 preptest books and did an exam a day during the month prior the December test. Fortunately, my memory is poor and most of the questions seemed new to me. Anyways, during my review, a lot of the things that Testmasters taught me were useful. I would try to find a good instructor. My first instructor left for Harvard Law School in September 2003 and the replacement was awful. Hardly anyone showed up to his class.
