LSAT is what counts, not gpa. I had an ugpa of 3.91 but my lsat was only 164 (needless to say, I got rejected at the top schools). I think if you are scoring in the high 170s on your lsat, you should pretty much get into the school of your choice regardless of gpa.
this is the ditch on the other side of the road. a 2.5 and a 170 will get you in just as few places as a 3.91 and a 164.
