Anon1997,
Is eating your meals at your sorority house an option? Do they have a study room? Like you, my daughter recently participated in a SEC recruitment. (Yes, my name is a dead giveaway. ��) She goes to her house for all three meals and to put in her study hours. She has met so many sisters and pledge sisters this way. I'm sure your judgement was right and you'll find "your people" soon.
