UC Reach Score is top-6 UC admits per 100 seniors in 2025, counted at each campus, so a student admitted to several campuses counts at each; a dash means the University of California published no admit counts for that school. Tuition, entrance exam, grades and application deadline come from each school's own admissions pages and are shown only where the school publishes them; deadlines already past are omitted. A school "publishes a counted college list" when its own published list carries a count beside each college; the three colleges shown are the three with the largest counts on that list. The list excludes nonclassroom-based online schools and schools the California Department of Education records with no 12th grade.
