It depends how low your grades are and how competitive your school's greek community is. If you are below the panhellenic required GPA, wait until you get your grades up. If you are just at the minimum for many of the chapters, then go ahead and sign up. You have nothing to lose. Worst case scenario is that you will have met a bunch of new people and have extra motivation to imporve your grades for the fall.

Have you talked with your parents yet?
