Are you instate for CA or instate for AZ?
What’s your parents’ budget - will you need merit aid, financial aid?
What’s your public HS’ average ACT/SAT (since your scores will be viewed in that context).
I’d say Stanford is a very high reach because of lack of national recogniation for ECs (the competition is that high)… so only apply if you’ve got the other applications done well. (No need to “not apply” and have regrets, but don’t prioritize it.)
Dartmouth, Duke, and USC are all reaches, obviously, due to sheer acceptance numbers. You may have a better shot at Duke and Dartmouth since you’d bring geographical diversity but only think of those after you’ve found your matches and safeties.
