^^^ Did he get rejected by any? Maybe a visit would have made the difference.
It’s not about one student. The facts support that generally, schools prioritize those who make the effort to visit.
I think the Ivies are the exception because their application numbers are so large, and the statistical qualities so high, that they don’t have an interest in A) administering the process of tracking visits, and B) dealing with all of the visitors on campus if it ever gets out they matter.
Highly selective LAC’s (I believe) use it a great deal.
