This case forms part of a collaborative marking project designed to support fellowship preparation. In the week leading up to each tutorial, you can contribute answers to any active case. If you contribute, your answers may be reviewed, marked, and used to refine the model answers during the weekly fellowship teaching sessions.

All responses are displayed anonymously or using anonymised avatars. You remain in full control of your answers and may withdraw them at any time.

Your personal results and updated model answers become available the day after the tutorial.

After the tutorial you can still do the case and self-mark your answers, but your answers will not be included in the group review.
