Is this UNC Chapel Hill? Great school, great college area!
Are you familiar with recommendations or "recs"? These are formal recommendations sent in by sorority alumnae on your behalf. There is a thread on Greek Chat that lists schools where they are mandatory to be considered for membership. UNC is listed in the "Up for Debate" category as to whether or not they're needed. UNC's Panhellenic website has a section about them.
http://www.uncpanhellenic.com/recrui...ation-letters/ They say they are not required, but I do a lot of these recs and my rule of thumb is -- if a school's Panhellenic website devotes a section to them, play it safe and get them.
Ask every woman you know who attended college if she is a sorority alumnae and if she'll give you a recommendation. She needn't be an alum of the actual chapter at UNC, just an alum of the sorority. She could have attended school anywhere. Ask relatives, friends of your mother, former teachers, women you know from church, those you babysat for, etc. For fall recruitment, recs are generally sent in the summer, so you've got time to line yours up.
Keep your grades up and go into recruitment with a strong GPA. Have you been involved in any activities this year? If not, see if there is something you can get involved with this semester. This demonstrates a desire to be a participant in things -- and you might even meet some more sorority members.
Best wishes to you!
