I actually think that some schools mean it when they say that GPA/LSAT isn't determinative. I was accepted at a top 15 school and a bunch of second-tier schools with a 2.15 undergrad GPA and a 163 LSAT (and I don't fall into any particularly favored demographic cohort).

how the hell did you do make it to a top-15 school with a 2.15 GPA??? you must surely have had a stellar (to say the least) essay.
