Does anyone know how much late LORs can affect your application? I've gotten some interviews (UCSD, UCLA, UW Seattle, Caltech), but it's kinda distressing that people are hearing from Harvard BBS (and I haven't yet). I was wondering if it's possible that they didn't consider my application because one of my recommender's letters is marked as being received 12/2/15 (past the 12/1/15 deadline). Is this something I could email them to ask about? Or should I just continue waiting until I'm officially rejected?
