You make a lot of excellent and valid points in post #34.
At ‘prep’ schools 100% of the kids are on the selective college track vs publics, where there could be a significant portion of students who aren’t going to college or are not competitive for selective colleges, so that does skew the numbers. At the same time, colleges do cap the % of kids they take from private schools. Many aim for a 50%private/religious to a 50% public ratio, so if you are a prep school kid you may be competing in a tougher pool.
