It depends on your campus. On mine, you had to have a 2.5 to even register for recruitment; chapter requirements were higher than that. GPAs were not rounded, and for good reason. Being a part of a sorority takes a lot of time, and if you have had a few semesters already then maybe you should concentrate on pulling up your grades.
Contact your university to ask them what they will do. I will say that if your GPA is under a 3.0 and you are an upperclassman, you probably won't be very successful at recruitment. Good grades are very important to sororities when they are considering new members.
