I’m not sure I understand. You previously said, “ (I beat some of the schools record times/around the same time level as their top swimmers), but I’m not sure if they are interested or not.”
I am not trying to play “gotcha”. I am suggesting that if your facts and assumptions are correct, you email each swim coach at each school and show how your proven, verifiable times stack up against that school’s teams, event by event, if you would be top 3/4. Be polite, modest, but factual.
I find it hard to believe coaches would not be interested if you are an impact swimmer in multiple events on their team. This is all relevant for schools that care about swimming - I don’t recall your list, but I believe it includes Andover, Choate, Deerfield, Exeter, and Hotchkiss. Perhaps some others with competitive swim teams as well.
