If the kids from your highschool getting into selective colleges tend to have hooks like legacy, athletic recruit, URM, Development, the data will not apply to you without such hooks. It was eye opening to see one prep schools private data on who gets in where as it was coded for those things and more. There was not one single unhooked kid who was accepted to Yale from there, out the many who were accepted over time. Not a single one. Princeton and Harvard, a little better, but the numbers were not good at a number of the schools, when the special labels became visible on the blips.
