ps - fwiw, going through formal rush isn't the only way to join a sorority. Most campus' have an "informal" rush that follows formal rush which is in place for the purpose of filling spots not filled during formal rush, still with campus rules, but all held individually and not including attendance at a bunch of parties at multiple chapters. Chapters can usually also add members at any time during the year too - if they have openings. So if your dd doesn't go through freshman rush, that doesn't mean she'll never have a chance to join a sorority.
