This expectation is what I find interesting. If this kid had the application which gained an acceptance to 3 of the most difficult schools to get into in the world, you don’t think the AOs at case western could see that the likelihood of that student going to their school was remote? Should they give the WL just to be nice? I think AOs are pretty adept at sniffing out those students.
As an example, a good friend’s S applied to Yale and Lehigh among others. He was accepted to Yale and was miffed that Lehigh rejected him. Why? If Lehigh had accepted him would he have attended instead of going to Yale? Of course not. It’s as if these kids just want to have bragging rights of getting in everywhere they applied to stroke their egos or validate their self worth. Lehigh wants to accept kids that will actually attend. Yield matters to colleges.
The OP asked a similar question: I was accepted by a great school but why didn’t all those other schools not want me too? There were so many factors besides just stats: international status, FA requirements, fit with the school, essays, recommendations…they all matter. I agree St. Olaf’s result is a bit baffling but perhaps it was the FA piece? Unfortunately colleges don’t provide feedback with their denials and waitlists. Most people tend to just focus on stats because it’s numerical and easy to compare, but that’s not the US college application system.
You also can’t compare the admissions environment that exists today with that of the 1980s and 1990s. More applicants and significantly different mission statements and acceptance criteria.
