Why you didn't get in.

I’ve said this for a while, but an American kid who is top 1 percent in everything (including 5’s on AP tests) these days, in the RD round, only has as likelies schools on the level of UW-Madison and NCF (which I still consider near-Ivies) as well as McGill/Toronto/maybe Waterloo in Canada, Edinburgh, St. A’s, Durham, Warwick, KCL maybe UCL in the UK (which isn’t bad at all as I consider them to be on the same level as UT-Austin, W&M, UNC, NYU, UW-Madison, and UMich/UCLA).
A decent chance at UCLA, Cal, UMich, NYU, UVa.
Also a good shot at Kelley@IU, engineering and CS at Purdue, maybe engineering and CS at UCSD or UT-Austin.

Lots of good/great opportunities at those schools. Between them, enough for almost all goals/interests, I daresay (if you can pay).
