I was one of the posters who liked OP’s style. It’s not the antics per se, and no applicant will say to the adcoms, “Hey, I blew off my entire homework process grade because I knew I’d ace the test.” It’s the type of person who does those sorts of things, but can still be very successful.
I guess it’s just a gut feeling. Let’s just say I’ve seen a number of kids like that at the very highest levels of achievement, including at HYP, and beyond.
