↵Notes: All regressions control for campus fixed effects, first-year fixed effects, age in first year, gender, an indicator for whether a student lives on residence, an indicator for whether a student is first generation, and a variable indicating (on a seven-point scale) the difficulty of transitioning to university. Standard errors clustered at the student level are reported in brackets. Significant at *p<0.10, **p<0.05, ***p<0.01.
