"Typical Harvard SAT scores are: Reading and Writing 710-800, Math 720-800"
Clearly, 1270 isn't up to snuff, especially for a white male, and, let's be brutally honest, Hogg would never have gotten accepted with a 1270 SAT had that shooting never happened. Hell, multiple colleges already rejected him, and he was waitlisted at UCF, and UCF accepts everybody.
Another thing to consider: Hogg is highly visible and, if he doesn't reconsider and does indeed go to Harvard, he will be very clearly stamped as the weakest white student on campus, and this by a wide margin. If I were him, I'd not want to walk that path. He may be too full of himself to think this through clearly. No one will laugh at him publicly. That would be un-PC. But they will all laugh at him behind his back.
