I've heard of previous applicants who ask their respective schools for feedback as to which aspects of their application they recommended that they work on. Is this only appropriate when the cycle is over or if you get rejected? Asking because I got waitlisted at two schools I interviewed at and I thought the interviews were great, so I'm really curious as to what was the determining factor of my application that made me get a waitlist instead of an acceptance. Would it be appropriate to ask them now, or is it better to wait until after this whole cycle and if I don't actually end up with an acceptance?
