Her weighted GPA is the UC GPA Fully weighted or Capped weighted?
UC’s consider 3 GPA’s: Unweighted, Capped weighed and Fully weighted and using this calculator will give all three GPA’s: GPA Calculator for the University of California – RogerHub
UC’s only use 10-11th grades for the a-g course requirements.
How is her HS rigor? What does she plan to do with a Biology major? Medical School? Dental School?
Biology is impacted at the majority of the UC’s and does not have a great ROI when it comes to post grad jobs if Medical school/Dental school etc… do not happen.
What other areas does she show interest? Public Health, Bioinformatics, Biostats are far more marketable but may require Grad school also.
I have some admit data not major specific for 2020 since 2021 numbers are not out based on the capped weighted UC GPA. Yes, a 4.0 will make her competitive for several UC’s but there is 12 other areas of criteria that the UC’s use in their application review although academics is Very Important.

Class rank is not a consideration for the UC’s except for ELC eligibility (top 9%) and she will be evaluated in the context of her HS.
There are no “easy” major admits for the UC’s but UC Riverside, Merced and Santa Cruz could be very good target schools.
I would also look into some top Cal states such as San Diego State, CSU Long Beach, Fullerton and the Cal Polys SLO & Pomona.
If graduate/professional school is in her future, keeping Undergrad costs low will be helpful.
Does she have SAT/ACT scores? Private schools of interest might be Occidental, Chapman, University of San Diego, Loyola Marymount, Santa Clara to name a few.
Much will depend upon what she wants to do with her Biology/Health related degree after Undergrad.
