UC campuses add 1.0 bonus point per semester for Honors, AP, IB, and transferable college courses. Those extra points are capped: only the first 8 qualifying semesters in 10th and 11th grade receive the bonus. A student who takes 10 AP semesters gets the same bonus contribution as a student who takes exactly 8. The result is the capped weighted GPA that UC admissions offices review.
Worked example: 6-course 10th grade year
For students tracking their 4.0-scale unweighted performance alongside the UC capped GPA, the high school GPA calculator covers the standard 4.0 unweighted method used by most non-UC schools.
Your high school transcript GPA covers all four years of grades in every class you took, including PE, electives, and freshman year. UC uses none of that directly. Instead, UC extracts only the grades from 10th and 11th grade in courses that meet the 'a-g' subject requirements. Freshman year performance does not factor in, and courses like PE, yearbook, and non-academic electives are excluded even if they appear on your transcript.
What 'a-g' covers (7 subject areas)
Not every section of every course at every high school is UC-approved. Schools submit their course lists to UC annually and courses can lose approval. Check your school's UC-approved course list before assuming all your classes qualify. For students planning ASU applications instead of UC, the ASU GPA calculator covers that institution's weighted system.
