For a self-certification extension no evidence needs to be submitted.
If you have used up your self-certification extension for this semester already, or you need a longer extension, or you were unable to submit your self-certification before the deadline, then you will need to use the standard mitigating circumstances process.
This means you need to submit evidence. Evidence is just anything that could be recognised as telling the university your story is true.
This could include (but is not limited to);
- Doctors letter/sick note
- Statements from a counsellor/wellbeing advisor
- Emails/correspondence from a landlord/housing authority
- Police report
- Death certificate/order of service
