The UC’s are very GPA focused so your capped weighted GPA will be a hurdle to overcome but an IB diploma will definitely show your HS course rigor. Your test scores and EC’s are very competitive, so if you write some compelling essays, there is a chance at all the schools but UCI and UCD seem the most likely.
Hopefully you have some safety schools on your list and best of luck.
