and the groups justify their choices of questions. These are commented on by the moderator with reference to the general principles presented in the lecture. What lessons were learned?

Students report that allowing the groups to justify their choices afterwards helps substantially in consolidating the principles of efficient disease classification. The competition has been highly rated in student evaluations for 3 years and is rivalled only by live patient demonstrations. In our experience, groups should be no larger than five students for maximum involvement in within-group discussions. With a total class size of up to 35 students, answering the questions posed by the resulting six or seven groups can sometimes be challenging for a single teacher. We therefore recommend a total group size of 25–30 students.
