This was quite a few years ago, but DS got into ND as an Applied Math major with Calc AB only as a senior. Came out of a Jesuit feeder HS though.

^PP, if not obvious, kid was admitted to Michigan and attends. Waitlisted Cornell ILR, probably due to sub-1500s level SATs, letters of rec probably not as tailored, compelling, also maybe yield protection. Cornell and Michigan are similar in many ways but Michigan in-state is $60K less/yr.
