Since you are a CA resident - I’ll focus on the CA Public schools. Privates can set their own rules, though most don’t stray far from the UC criteria.
UCs - all of them - use the same application and criteria but tweak things a bit (like GPA cap).

They boil down to:
Did you take the requires a-g classes? (if no, you are out)
Academic GPA (they call it UC CPA which focuses on academic courses in grades 10-11 and is capped at 4 semesters of AP bonus credits. For good measure, they drop +/- as well. Easier than it sounds, use this calculator:

Standardized Test Scores
Rigor of your academic courses
Performance relative to opportunity available
Special Talents/Skills and Achievements (this includes sports, class officers, clubs, eagle scout, etc)
Eligibility in Local Context (top 9% of your class)
Location of your school
- to some degree your essay.
The UC system says they weigh test scores and GPA at about 50% - truth is, it is probably closer to 80% in most cases. It takes an exceptional applicant to overcome sub-par GPA and test scores. Also, most value GPA over test scores.
You can use this page to see ave GPA and test scores for last year at all UCs here:

In general,if your GPA and SAT are in-line with the average, you have a very good chance of gaining admission.
CSUs (not CalPoly SLO) us a much simpler formula.
They too put a brick wall up for students who didn’t complete the a-g course list with C or better.
CSU GPA * 800 + SAT (M&R) - there’s an ACT formula too. (Also some campuses use a different formula for STEM applicants) - notice there’s no place to put Eagle Scout, Class President, Captain of Football Team, etc in this formula. Also CSU GPA = UC GPA
So 3.5 GPA and 1200/1600 SAT give you an index of 4000.
That is it… CSUs simply stack up applications by Index and stop admitting when the seats are full.
Most CSUs set a lower threshold for local high school grads. SDSU (the most selective CSU using this method) is looking for about 4100 for out of area (but in state) applicants and probably 3500 for locals.
This method really clouds their admitted student data. A non-local applicant with ‘average’ GPA and SAT at CSULB or SDSU won’t gain admission.
A few other popular CSUs
Long Beach - 3850
Chico 3700
Fullerton 3700
CalPoly SLO uses a system of it’s own, kind of a hybrid. read all about it here:
