An attempt to achieve problem-based examining by the structured assessment of presentations is described. Students can choose to participate in the scheme in teams and then elect to use their awarded mark instead of part of the formal examination assessment. The element of choice of the study or examination method is seen as being a valuable element of the scheme. The scheme can be introduced without radical revision of existing curricula or substantial investment of staff time, and meets some of the expressed desires of the UK General Medical Council in terms of the introduction of novel methods of assessment.
