Although the UC’s are test optional now it still does affect your chances of admissions. Schools in the top ten of US News and other college ranking list want to see a “spike” significant accomplishments in a singular area. They don’t want to see well-rounded applicants contrary to popular belief. Based on what you’ve done I would say you have a really good chance of getting accepted to UC Berkeley. I also think you could get accepted to Stanford if you applied. Good luck!
