I know what you mean ElizaB. I'm as nervous as a you-know-what in church waiting for the decision. Here's my latest theory, probably not worth the virtual paper it's written on, but oh well:
If you look at LSN, you will see there are some people who had lower index scores than those who were deferred but they were still accepted early decision. These folks w/ low indexes who still got accepted all had a high LSAT low GPA split.
Looks like UT really focuses mainly on the LSAT. From these preliminary results, it looks like you can have a pretty weak GPA in a somewhat soft major and you can still get accepted ED if you have a 167+ LSAT.
Hopefully in regular decision they'll actually read the applications and make decisions based on all the other factors besides just LSAT.
