As to how it calculates the GPA, it does not look at test scores, it just does the following:
- Convert the grades earned in all college-preparatory courses ("a-g" courses) taken in 10th and 11th grades, including summer sessions: A=4, B=3, C=2, D=1. (Pluses and minuses don't count.)
- Gives an extra point for each honors-level course, up to eight semesters.
- Honors courses are Advanced Placement courses, Higher Level and designated Standard Level International Baccalaureate courses, transferable community college courses and UC-certified honors courses that appear on your school's course list. A grade of D in an honors course does not earn an extra point.
- No more than two yearlong UC-approved honors-level courses taken in the 10th grade may be given extra points.
