Students need to study 120 credits per year, this is usually 6 modules, each worth 20 credits.
Many of our programmes offer an optional module worth 20 credits from an alternative faculty, you can find more details in the Faculty Handbook.
Studying an optional module from a different department may be restricted timetabling and availability of places on the module you wish to study.
If you have any queries about this when you being the registration process your department will be happy to advise you.
