I don't know that I'd say she isn't a grade risk. She got great grades, switched schools and then they plummeted by nearly a full point. While I would be willing to bet the new school came with some understandable growing pains, reports say your first semester in a sorority also comes with grade drops (the study which I can't site here but is lurking SOMEWHERE on GC) regardless of whether that pledge period is as a first semester freshman or later on. They pop back up again, presumably once you've learned to juggle your increased responsibilities, but in the meantime I would assume that in the short term she could be at risk of a further drop.

There isn't anything you can do about it at this point, so I would try to provide as much information as you can (and this is a good reason to use recs, even if you go to a school that doesn't require them), accept any invitations you are offered (this is no time to think you are the chooser here), and be as fully prepared as you can be.
