I think she means Tennessee, still very competitive but I don't know a lot about it. Anyone?
Here's all I've got: There are 13 chapters at UT so you'll probably need more reference letters. Bumping up your GPA will help you a lot. Finish strong!
Buy a white dress (pure white, no colored trim) - a simple shift is ideal. Get it from a store with a liberal return policy and leave the tags on it. Then hang it in your closet and forget about it till you're packing for college.

Yes, I do mean Tennessee. And unfortunately a 3.09 would be best case scenario
Sounds like you've got a good start. Get recs for every sorority. I'll add the standard warning about keeping an open mind. UT has a strong Greek system, and every sorority has something to offer. Don't get caught up in tent talk, trust the process, and enjoy your remaining months in High School.
