I was wondering if anyone has any feelings and thoughts about Testmaster's or Powerscore tutoring services. I took the Testmaster's course last summer, took the Oct09 test and canceled my score. I'm giving it another go and have been self-studying for 2 months on my own. So far, I haven't made that much progress (still scoring in the 150s

Both TM and PS charge $150/tutoring session which is pretty steep to me. Do you guys think it's worth it? I don't want to continue sinking money into LSAT Prep unless it's going to help.
Thanks for your thoughts!
