I was kind of wondering the same thing. I'm getting a b.s. in Biology and realistically, I'll end with 3.5-3.7 GPA at best (at the University of Minnesota) so I'm wondering how they might weigh that compared to say, an English degree with a 4.0 GPA.
Schools will not evaluate an incomplete application package. You can submit an application prior to receiving your LSAT score, but the schools will not look at it until LSAC has sent them your score.
