“Several years ago” may not do it, as the number of apps increases annually and expectations rise.
Again, the fact a college had x% of some factor admitted (or matriculated) tells nothing about criteria. If a college reports x% from public hs, does it mean you have an advantage coming from a public hs? No.
Remember, with single digit acceptance rates, these colleges cherry pick, in the end. They can’t justify taking any Val or Sal who doesn’t pass their holistic muster.
Look at Brown. Why do you think they rejected 81% of vals? Can’t be they were 3rd in their class, lol.
