The first, sometimes the only, selection tool for entry into undergraduate medicine is prior educational attainment (PEA). This is often further specified to include certain subjects, for example, biology is a prerequisite for entry into medicine in many Asian countries. However, there seems no clear evidence base for this prerequisite. Our aim, therefore, was to carry out a retrospective quantitative study comparing the performances of five cohorts of students (2015-2019 entry; n = 588) with and without biology PEA in Years 1 and 2 Bachelor of Medicine and Bachelor of Surgery (MBBS) integrated written assessments (n = 3) and anatomy practical examinations (APE) (n = 5). The study was conducted at one of Singapore's three medical schools. Data were analyzed using independent t-tests and Mann-Whitney U with p values of less than 0.05 were considered significant. There were no significant differences in performance on any Years 1 or 2 integrated written assessments. Similarly, in one of the APE, a significant difference was found for one cohort (academic year [AY] 2015-2016) out of five assessments. These results suggest that having a prior biology qualification does not make a difference in assessment performance in the early years of medical school. This information may help stakeholders and admissions committees decide whether biology is required for medical school entrance.
