Sorority Recruitment

Hey there! I’m South Bound in the fall and am signing up for sorority recruitment. I have good grades, involvement and a positive social media presence. Do I need a social resume and recommendations? If I don’t need them, will they be beneficial? I don’t want to overlook anything. My sister is a Chi Omega at Alabama and I know there’s a Chi O chapter at South, but I don’t know if it will matter.
