From what I can tell, your chances at a 1L biglaw summer gig are slim unless you know somebody, or unless you're a non-white female. Most 1L jobs at big firms are reserved for "diversity fellowships" or something similarly named. With your numbers you've got a good shot if you're "diverse," but it's tough to get a slot otherwise. Good numbers so far, though I agree with the above, I'd wait until all your numbers are posted.
