As for TM v PS v Kaplan, I'd say stick with what you've already paid for. I have seen all three programs, each has its merits (except TPR... muahahahahhaaa) but Kaplan has the best online stuff, test explanations for every question and the Higher Score Guarantee. My question to you is have you been using the Pacing/Endurance/Mastery books? How much work have you put into the class?
I'll try to ignore your cheap shot at TPR (although I don't believe I've ever taken one at Kaplan...tsk tsk)
Couple questions, however, that I'd like to hear from a real instructor.
What makes their online stuff "the best"?
What do you like about their test explanations
What does the score guarantee entail?
Does Kaplan rearrange the order of questions in their games?
Does Kaplan require their instructors to take the real LSAT?
Does Kaplan train instructors of different subjects together?
