EG1001: Yes, I've applied to both schools in NC (and are the only ones I've applied too). My AADSAS status says they were complete on 8/6, but I submitted my secondaries a couple weeks after that, but ECU had a really fast turn-around and I found out about an interview for Nov. 2nd.
I think that Nov 6th is the last pre-dec interview at UNC, so I hopefully hear from them in a couple weeks.
Regarding the academic accomplishments of the members of this forum, yes it is rather humbling to be merely be in the 70th or 80th percentile, but every person offers something very different. If I can land an interview, I'm sure just about anyone can. Good luck!👍
