I can't speak of how things are at U of Oklahoma, but at my chapter, we pay attention to everything about the rushee, not just the GPA. In the past we've extended bids to girls who haven't quite met the required GPA (who've basically been borderline like you are)...but because there was something about them that we liked, we knew that we wanted them to be a part of our organization.
HOWEVER, if we get a large number of girls, then their GPA may be the key in determining who gets invited back and who doesn't.
Good luck at U of O and please keep us posted. I checked out their Panhellenic website and their houses are simply beautiful.
If there are other questions you may have, please check out the Sorority Rush FAQ in the Announcements section.
