You have to objective. You can’t be when it’s your daughter. I’m assuming with the grades and weighted gpa she has rigor. But there is more than grades. And when you are applying to the top schools, everyone is like you. You have said which UC but the top schools are not easy. So you need match and safeties.
Some schools admit to the school, not major. Others admit by major.
You can see impacted majors at the UCs. Today Es is very popular and looking at the impacted list for UCs I see it. Again, you need to be objective. I would do research and not assume.
With her gpa, etc she’ll go near free at Arizona, Alabama, dirt cheap at Florida State and there’s so many more. These schools are bringing in smart kids from all over and putting them in their Honors Colleges. With those grades you might also look at W&L and the Johnson Scholarship
Good luck.
