yea, i am also at a similarly ranked school and the curve is 3.2 so a 3.39 is at least top 35% here. However, you guys may not have the grade break downs. Anyway, I think she may have a decent shot. Or, at least, her chances arent terrible. I would suggest to her that she start emailing alumni from UT at firms in LA and just asking for general advice (prepping for OCI, anything she can do to make herself more desirable, how they felt the transition was to LA, what classes they would recommend because they enjoyed a lot, anything like that). I mean, if she starts now, she can have a few contacts just to drop a word with later on and say hey i talked to you before and decided to apply here. I think that some early preparation might help her out a little in the process.
plus, she can get a better boyfriend
someone that helps her study a little more. jk.
