The major examination periods are timed to accommodate the requirements of each individual degree programme and you may therefore find that you have an exam scheduled during a particular religious festival or period of religious observance.
If this is the case you should speak to a member of your department, normally the Senior Tutor or Postgraduate Tutor as soon as possible. Your tutor should listen to your situation and discuss potential solutions with you, although it will not always be possible to find a solution.
It is not normally possible to reschedule an exam but in some circumstances it may be possible to put arrangements in place to accommodate students who are, for example, fasting or who require time to pray.
You may also wish to discuss your circumstances with a chaplain or faith advisor from the College Chaplaincy.
Full details of the Colleges policy and procedures for exams and religious obligations are detailed in the Examinations and religious obligations [pdf] policy.
