Whilst the University will make every effort to offer the modules listed, changes may sometimes be made arising from the annual monitoring, review and update of modules and regular (five-yearly) revalidation of programmes. Where this activity leads to significant (but not minor) changes to programmes and their modules, there will be consultation of students and others. It is also possible that the University may not be able to offer a module for reasons outside of its control, such as the illness of a member of staff or sabbatical leave. Not all optional modules will be offered every year and programmes will inform students of the optional modules running for their next year of study in good time to assist choice. Some optional modules can have limited places available and so you may be asked to make additional module choices in the event you do not gain a place on your first choice. There are also minimum numbers of students required for some optional modules to run. Where the first choice does not run or there are insufficient number for the module to run, the University will endeavour to inform students promptly.
