Again, someone can correct me if I'm misinformed....
To address your points:
a) During rush, they don't look at your SAT or ACT scores, at least not that I've ever heard of. And yes, you may be intelligent, but there are other girls who are also intelligent and capable who have proven it with higher GPAs
b) I don't know enough to accurately comment about legacy status
c) And being accepted to the leadership program is great, but especially at a competitive SEC school, I don't think it would be enough.

As ASTalumna said, National offices set GPA minimums, but individual campuses/chapters may require higher than that national minimum depending on the campus culture. RARELY exceptions can be made if you are a grade risk and have a GPA slightly under what an individual chapter desires if you really really wow them. The problem is that you are below the national minimum, therefore chapters have no choice but to release you. Not to be harsh, but merely to put it in perspective, at an extremely competitive school with so many girls going through rush, why should any chapter bother to take someone with such a low GPA when there are so many other "shining star" contenders who do have the grades?

In my personal opinion, because you are almost definitely going to be released, I think it's not only a waste of money to rush, but I don't feel that girls should rush just to meet people without the intent and actual possibility of joining because should you be invited back to another round, only to be dropped the next day for grades, you could be taking the spot of another girl who really did want to be there.
