Dead on arrival. Correction: your application would be DOA at T20 schools. Also, find it amusing for someone to be so wrapped up with prestige with a 502 MCAT. Your MCAT is barely average and you’re indeed extremely fortunate just to be accepted. If you want T20, drop your acceptance and reapply. No one here will empathize with you. You’re in an extremely envious and fortunate position. And you’re whining about T20 schools.
DO Ortho attending btw, no one cares about where you went to Medical school, not even if you’re MD or DO once you’re out. I am busier and make more money than all of my MD partners, as a lowly DO. So much for prestige.
