My kids attended a public non-magnet HS in a flyover state. Each year the graduating class was around 300. From my son’s class one went to Princeton, one to Harvard, one to Columbia, one to Brown, and one to Amherst. My daughter’s class sent one to Harvard, one to Stanford, one to Duke, and 2 or 3 to UPenn.
This HS ranks its students and there is high correlation between rank and acceptances. Of those listed above, all were in the top 3% in rank.
