Comparison of the award gaps in the exam, coursework, and final mark, for first class marks only (A, C) and all good marks (B, D) for the year 2 and year 3 average (A, B) and individual (C, D) cell biology courses and cohorts in year 3 (also listed in Figure 3—figure supplement 1—source data 1). As noted, cohort 4 of year 2 was excluded from Figure 3; therefore, for fair comparison, the award gap data shown here for year 2 only includes cohorts 1, 2 and 3 for all good marks and first class marks only. Award gaps in all four year 2 cohorts (cohort 1, 2, 3 and 4) were similar except the exam gap in all good grades is larger (~18%) for the 3-cohort mean (B) than the 4-cohort mean (Figure 2E, year two exam,~13%) as expected, and this also follows through to first class grades (see full evaluation in Figure 3—figure supplement 1—source data 1). All award gaps represent the mean of individual cohorts or courses except those in year 2 at the level of first class marks (see Methods for more details); the exam gap was instead based on the aggregated data of cohorts 1–3 and, for a fair comparison, this method was also used to calculate the award gap in first class marks for the other two components (final mark and coursework). See Figure 3—figure supplement 1—source data 1 for mean values +/- SEM or averages as indicated.
