Indeed, you need ADLC for HYPSM. MIT to its credit does not use Legacy, and I reckon they don’t use Athlete. MIT requires SAT, but Caltech doesn’t.

All this to reiterate a point from the start of this thread, that colleges are often hardly about rewarding intelligence.

Mithawk, what would your advice be for DYS for college admissions?

My view is the higher ranked colleges are worthwhile. They can often be inexpensive, after Princeton initiated the practice of simply giving grants and not loans. I think most parents want their kids surrounded by inspiring classmates. The schools can make you aware of, and open, doors you might not have known existed. They have abundant resources. You don’t have to commit to an impacted major like CS while in high school, and can generally wait until you’re a Junior to declare your major.
