Super-selective schools want you to have high stats just as a baseline (unless you have a super-hook or something else extremely unusual that they like). They then use other factors to determine whom they admit out of a large pool of high stats applicants.
Unless you have a super-hook or something extremely unusual that they like, you basically need high stats and some high level achievement or award in an EC or some such, and no “defects” (in such things as recommendation or interview).
