For last year's applicants: Did anyone have their LOR packet returned by a school for not having it in the proper format? For example, for sending 4 letters instead of 3, etc. I've heard most schools accept additional lor's, even if they request only 2 or 3. However, has anyone had a school complain about extra LOR's being sent? I don't want to call every single school and ask how strict their guidelines are, maybe I will need to though.
