I have been lurking around this forum for a few weeks now and have learned much from the forum. I decided to take a live prep course based on my TM diagnostic test score of 143. The forums topics I have read basically stated the pecking order for prep classes as follows: Testmasters / Powerscore / Manhattan > Princeton Review > Kaplan. However, many of the posts were a few years old. Is this still the case? Should I take TM course with a starting score of 143 or go with PR or Kaplan? Also, I also know the instructor is who will make or break the class for me (I spoke to Kaplan and TM today but they had not assigned an instructor to either class yet). Has anyone taken any of these classes in the metro Detroit area and what was your experience?
