Just an FYI. All the UC’s and Cal States use 10-11th grades in their GPA calculation. The exception is Cal Poly SLO. 9th grades are also factored into their GPA calculation.
The Cal States (except SLO) only really use UC/CSU GPA and SAT (Math and Critical Reading) score or ACT composite score to calculate their Eligibility index. EC’s are very minor in admissions consideration for the Cal States. Once you have your CSU/UC GPA you can calculate your EI.
(CSU GPA X800) + (SAT M+CR) OR (CSU GPA X200) + (ACT composite x10).
The Cal states rank each applicant by major based on EI. They then accept from the highest down until the spots are filled.
Although SJSU is the only Cal state that consistently publishes their EI cutoff, several will state a minimum required especially for impacted and competitive majors.

Some EI thresholds to consider:
SDSU: 4100+ SAT/1000+ ACT
CSULB: 3900+ SAT/900+ ACT
CSUF: 3800+ SAT/850+ ACT
Chico state: 3700+ SAT/800+ ACT
Much will depend upon intended major. The more competitive the major, the higher the EI threshold.
This will give you some kind of guideline for determing major, needed test scores and GPA to make yourself competitive and to come up with a balanced college list.
