No, I submitted all the required stuff so it's not that. I normally wouldn't appeal something like this, but I really feel I was well qualified and I don't think there was anything "clearly wrong" with my app. since I got interviews at UCSF and UCSD. I've seen people appeal pre-interview rejections for med school and some have gotten an interview as a result. Anyway, I think I'm going to go for it since I don't have anything to lose. Thanks for the replies.
