Ethnicity not considered in California public university admissions.
She has some excellent EC’s and if her personal insight essays are equally outstanding, then some of the Mid-tier UC’s are very possible.
Since her intended majors are usually housed in the College of Letters and Sciences which does not admit by major, it will not give her a significant bump in admissions. She will be competing with all L&S majors.
Best of luck to her.
