[33girl]

If you trust that you've raised your daughter with good judgement about people, she will be able to see that either 1) these girls are really the Hot Mess Express that everyone thinks they are or 2) the situation has been completely blown out of proportion (the fact that grades are the first thing you mention and that the alleged "altercations" are the last tells me something) and they're simply the less popular chapter. If that's who your daughter feels at home with, then that's who she feels at home with. It may be she would rather have 2 semesters as an active with women she truly loves and who will be lifelong friends, rather than the chapter that she picked just because they seemed "sturdy."

If at the end of rush week her situation is the hypothetical you've set out, and she would rather not be Greek than be in this (or any) sorority, she should NOT write their name on her bid card.
