do colleges really throw out apps that don't meet the gpa and sat/act requirements first?

However OP asked

Which clearly doesn’t make sense.

FYI I have a friend on an adcom at a HYP. He told us the ivies don’t all look at applications the same way (surprise!) but at his, they will properly examine any application with a B average or higher. And while most of the admits at that range might be hooked, not all of the admittances below the median are, at least not in traditional ways. There are many ways to put a class together, and if an athlete with a B average in high school can get by academically at an ivy, so can anyone else they find particularly interesting. Is it common? Of course not. Does it happen? Yes.
