I will say after visiting and talking to a lot of people, this was a bit of a concern of mine as well about Wake. My S24 is social enough to get along fine with the sorts of kids at his HS who then have gone on to love the social scene at Wake, but his actual core friends were not really those kids. On the other hand, I think Wake is sometimes an underrated academic opportunity, including because of all the real focus they put into excellent teaching and student-professor relationships.
So I think for the right kids, Wake is a fantastic place to combine both a traditional sort of college social experience with a top-shelf educational experience. But if the former is not what you are looking for socially? Not necessarily insurmountable but worth thinking about.
