Confidence is reported on a 1–5 scale from “No confidence” to “High confidence”. Current understanding is reported on a 1–5 scale from “None” to “High”, while knowledge compared is reported on a 1–5 scale from “Much less than others” to “Much more than others”. Test results are reported for paired comparison of T1 and T4. Total number of valid responses shown at each time point. The objective knowledge measure, range 0–10, was only included in 2014–2015

^aWilcoxon-signed rank test between T4 and T1, and thus only including eligible students

^bOnly 44 participants answered this question at T4

^cWilcoxon-Mann-Whitney test of association with year was not significant: Z = −1.11, p = 0.27

^d Wilcoxon-Mann-Whitney test of association with year was not significant: Z = −1.27, p = 0.21
