It’s so interesting to read this. When I look at the scattergrams at my daughter’s school, zero accepted to Yale, Harvard, Columbia, Dartmouth, Penn, Stanford and MIT! There was one to Cornell and a few to Brown but not for several years. I’m just pretending that I didn’t see the scattergram. That’s really cool that you can gauge the chances a bit better coming from your son’s hs; it sounds like an extraordinary place.
