National champ but bad GPA progression

“Can be,” sure. But adcoms at places like Harvard (which OP initially named) don’t need to take risks on kids who don’t follow the usual, basic “rules.” This isn’t budding genius. It’s not creativity. It’s blowing off the basics.

I do like a little bending of rules, etc. But if that’s his purpose, don’t aim for Harvard. Maybe look at Hampshire. Harvard is going for proven stuff, kids who keep up. They’ve got 39000 lined up.

So OP, make wise choices. If you want to go your own way or chart your own path, do it with more significant challenges than blowing off homework or the SAT. Make a real difference.
