Hey there! I'm a Sophomore at Harvard who's helping run HAIST. Congrats on your acceptance to Harvard! :) Some initial thoughts, which others might disagree with:
Harvard being inflexible seems wrong. My impression is always that all "prerequisites" are merely suggestions; to get around them, simply shoot the professor a very quick email. Taking grad classes is pretty common; I was taking one this semester, and a (Harvard) friend of mine has taken a few grad MIT classes in his Freshman and Sophomore years (both my and my friend's classes were CS classes).
Hi Naomi!
The advice about applying to MIT/Stanford is probably correct, if just to have the option. That said, I definitely don't regret ending up here!
