If you are unable to study for a period of time due to extenuating circumstances, you can request a deferral (study break) during your unit.
For a short deferral (3 months) you will not need to provide supporting evidence - this can only be done once per unit. The maximum deferral(s) time is up to 12 months per unit in total.
There is guidance in the Student Handbook about applying for deferrals, including the forms to apply, and the extenuating circumstances policy.
Once you have checked you have grounds to apply (section 12 of the policy) and arranged appropriate supporting evidence for deferrals over 3 months (section 13 of the policy) you can submit your application via the helpdesk, or via learnersupport@oca.ac.uk
