I agree. Try getting a recommendation from somebody that knows you quite well (like one of your sports or club leaders) as it gives admissions a better conception of who you are. I’d definitely say you have a chance at Harvard, but it’s so selective that there’s no guarantee, especially since your an international. Congratulations on what you’ve accomplished thus far and good luck!
