The A-G College Entrance Requirements
The University of California (UC) and California State University (CSU) require entering freshmen to complete certain courses in high school, commonly known as the "A-G requirements". To meet minimum admission requirements, you must complete 15 year long high school courses with a letter grade of C or better.
Keep in mind that taking approve high school (A-G) courses is not the only way to satisfy these requirements. You also may meet them by completing college courses or earning certain scores on SAT, Advanced Placement or International Baccalaureate exams.
