While I do hold my sorority experience and sisterhood in high regard, it isn't as valuable to me as my college education.

Look at it this way...what if you don't get a bid at a less-competitive school? Even though the campus may not be as competitive as UT, you're still not guaranteed a bid. What are you going to do then?

The decision is ultimately yours, but my suggestion is to put your priority on that UT education. I doubt that anyone here on GreekChat will tell you otherwise.
