I would say that any courses that are in the a-g Course List for UC/CSU would be counted for the UC GPA. Your HS obviously wouldn’t be listed since it is out of state, but you can type in the generic name of the course to see if other in-state high schools get credit for it or not. Look here: https://hs-articulation.ucop.edu/agcourselist
So courses that wouldn’t count would be things like PE or Weightlifting or Golf. But most everything else probably would count, whether it be a certified HS online school or at a community college. Even courses like Beginning Dance, Ceramics and Auto Repair would count. The courses you took in college probably would be considered weighted (I think) as well.
So it sounds like you’re more closer to 24-28 semesters in 10th and 11th grade, as opposed to 16 semesters. Which would be better for you if you got As in all of those extra classes. Also, some of the college classes that was taken as one semester might count as two semesters for UC GPA calculation purposes for certain classes (not sure which ones they are).
