UC’s are test blind through the 2025 admission cycle. You are doing well but remember the UC’s only consider 10-11th grades in their GPA calculation.
I agree that Physics Senior year will make you more competitive and replace Stats with Pre-Calculus since both courses will be part of the Biology curriculum at the UC’s and Stanford. You want a gentler introduction to these subjects in HS vs. College.
Also you might want to reconsider Biology as a major since “pre-med” students need a viable back up if Medical school does not happen. Biology majors are a dime a dozen so Bio stats or Computational Biology can make you more marketable and would require higher levels of Math.
I am assuming your Arts course over the summer covers 2 semesters at your HS or is this a CC level course?
Best of luck.
