The question you should ask is not what is the lowest LSAT score accepted. You should ask, what's the lowest lsat that's been accepted at a Tier 1 (Tier 2 possibly) law school. I don't know that you're going to recieve any serious responses to this post (why are you writing in all caps?) Go buy the Powerscore books, take at least 25 prep tests, if not more, the more recent the better. I know you didn't ask for studying tips, but judging from the posited query, I'd venture to say you could use a couple. Good luck in your studies.
Oh yeah, when you take those prep tests, each question that you get right and wrong, know the reasons behind everything.
