Your GPA is good enough to get into a 1st tier school, but what matters most is your LSAT. I would suggest buying a few books, I tried:
Kaplan 2 real LSAT's explained
Logic Games bible
10 real LSAT's
The reality is, your chances of getting into a school are dependent on:
50% LSAT
40% GPA
10% other
it helps if youre a minority too. Hope this helps, and good luck.
