Welcome to College Confidential as a first time poster.
The first thing you need to know is the UC’s only use 10-11th grades for the a-g course requirements for their GPA calculation. Freshman grades are reviewed to make sure you passed your a-g courses and you need to pass all your Senior courses with a C or higher but since the application is due Nov 30th, Senior grades are not considered in your admission decision.
Here is the Calculator for the UC GPA. Please post your capped weighted UC GPA which is used by all campuses and also your fully weighted UC GPA which is considered by UCB and UCLA also.

Your SAT is low for competitive majors and UC campuses so aim for a 1450+.
Attending a competitive HS will be considered but your whole application including essays, EC’s, SAT subject tests etc… will be evaluated for admission consideration.
The UC’s tend to be very GPA focused but due to the increased competitiveness of all the campuses, you need the whole package. Being female interested in STEM is not an advantage at the UC’s, perhaps at some private LAC’s it might give you a bump.
I suggest you look over the UC Freshman profiles for each UC campus of interest and see how you compare.

I also suggest you apply widely to the UC system, consider some competitive Cal States and identify 1-2 safety schools before focusing on any Reach schools like UCB.
