Well, OP’s DD should be hearing from Emory soon and then , it’s game over for them. Fine school, not settling , a lot of kid’s first choice reach, and if it doesn’t work out, she has her safet which was one of my kids’ first choice school as a safety. In a good place.
The info I have for our area schools shows more accepts for MIT and a number of Ivies over UNC -CH, but it doesn’t mean that the latter is more selective here. Those who applied to say, MIT, are not necessarily the same kids who applied to UNC. In fact, none of the kids I know, and I know quite a few of them, over the years here, who applied to MIT also applied to UNC. One of mine contemplated applying to UNC , but had he done so, it would have been one of his high reaches, and he was not looking at HPYMC etal. They would have been lottery tickets for him.
