About the numbers
Historical grade data from the Daily Nexus, obtained from UCSB’s Registrar through public records requests. Available records extend through Summer 2026. Course history is not a list of current offerings. Dataset retrieved .
GPA and grade percentages use letter grades only, weighted by the number of grades. A range includes A+, A, and A−. Repeated enrollments count separately. Past grades don’t predict your result or a course’s workload. How to read grade distributions ↗
