Your eligibility index is (3.5 x 800) + (1300)= 4100. All the schools look like a Match. Best of luck.

I agree. assuming you have completed the A-G courses and that’s your CSU GPA (grades 10-11 and academic courses and capped at 8 semester AP bonus points) you are a competitive candidate for all of those schools
