  1. Notes: Each column contains coefficient estimates from separate regressions. Each regression also contains controls for race/ethnicity, UC-adjusted high school GPA, parental education, family income by cohort, college, college selectivity tier by cohort, and UC application-admission pattern fixed effects that account for the intended major listed on each application. Robust standard errors, clustered by campus, are reported in brackets. ***p < 0.01, **p < 0.05, based on a t-distribution with 5 d.f.
