But doesn't Grutter say that (public) schools can't arbitrarily add weight for being of X race, and have to view the candidate holistically, contribution to diversity, etc? Isn't that why they ask candidates to write diversity statements?
(Of course, for private schools, that decision is irrelevant, but good luck getting a private school to say, "Sure, we give bonus points for being __!")
That aside, are you saying that Hondurans (for example) are NOT under-represented in the legal community? I'd be surprised if that was the case.
Personal advice to OP: Don't count on being 1/4 Hispanic to get you in, but certainly do spend some time on the diversity statement and make it sound compelling. Your GPA is very good, so I would also second the advice to re-take in October if that seems feasible. I wouldn't be surprised if you got in some really top schools with money if you had an LSAT score that matched the rest of your profile.
