As far as I know, they look at the LSAC cumulative and not the degree GPA. Even if they do, its not that big a diff. I wouldn't worry about it.
Awesome, thank you all for the information. In relation to my transcripts, my worry was that in addition to my GPA, they would actually look at the grades I received for the courses. I know they put more emphasis on the overall LSDAS GPA, but do they factor in your actual course grades themselves when making a decision?
