BACKGROUND: Senior medical students organised and delivered a teaching day to prepare an academic year of junior colleagues for their end-of-year objective structured clinical examination (OSCE). METHODS: The day involved a series of mini lectures, followed by group-based teaching to reflect the various stations in the proceeding examinations. Feedback forms were completed at the start and end of the teaching day. RESULTS: As indicated through feedback, senior medical students are capable of organising a successful revision day to prepare more junior peers for their end-of-year examinations. DISCUSSION: Having completed the same set of assessments, senior medical students are well placed to prepare more junior colleagues for their examinations. This exercise offered valuable teaching experience for the tutors, and also highlighted numerous areas of development for future iterations. As found in other such projects, this approach was also rated as effective by the participants.
