Gunmo - how did testmaster help with your test score?
TM raised my score significantly. But like Gummo said, you have to memorize concepts in class b/c there is nothing in the books but LSAT questions. It kinda sucked, but I took notes directly in the books which helped. However, my instructor spoke really fast so it was super difficult. Anyway, I started testing at a 153, and raised my score as much as 12 points during the practices. I would take Powerscore if you can b/c their LG Games bible really helped me, and their classes are supposed to be super small. Mine was huge and disruptive. It is essentially the same material. Good Luck!!
