I know that our campus requires a 2.25 for rush, and since you make that cut, you're eligible to rush. Sororities will look at your GPA, but if you represent their values and ideals, they will look past the GPA to you.
I know we had a chapter with a woman whose GPA was very low, much lower than yours, and they took her as a new member, and gave her a lot of scholarship support. She got a 3.4 during the semester she pledged, and has done really well since pledging.
Don't let your grades hold you back. A sorority is much more than a group of friends. We have resources to help those who may have academic problems, so use them
