Evaluation of anatomical examination difficulty between the 2018–2019 and 2019–2020 cohorts. The difficulty of theory and laboratory examination of anatomy course between the 2018–2019 and 2019–2020 academic years was evaluated by four testers who were teaching assistants of anatomy course but blind to examination questions. Each score of testers’ midterms (mid) and final examinations (final) of two academic years was shown as a scatter plot. Pearson’s correlation coefficient (r) was used to measure the correlation of examination difficulty between the two academic years. Significant correlation was demonstrated if p < 0.05. The results of theory (A) and laboratory (B) examinations both showed strong correlation between the 2018–2019 and 2019–2020 cohorts.
