For Part I coursework sessions, once the teaching office has approved the re-arrangement request, students should identify an appropriate replacement slot in the timetable, in discussion with the appropriate lab technician or lab leader. Alternatively the lab leader may offer an equivalent exercise, such as an online version of the lab.

For activities that extend over a longer period such as exposition, "re-arrangement" may consist advice on catching up with the task rather than a substitute session as such, in this case no penalty marks will be applied for non-attendance at a session if teaching office approval is given.

Contact details of lab leaders and technicians are available online: IA, IB.
