In the event of an extension approval being sent to you after the extension date has passed, contact the Assessments team by raising an enquiry via the Student Enquiry Centre as soon as possible. This can then be investigated for you.
There is always a risk that you might not receive your outcome until after the original deadline, particularly at busy times of year (eg. ahead of key assessment periods). If this happens the Extenuating Circumstances policy (Meeting Coursework Deadlines) clearly states that if you have not received a decision on your EC claim by the original deadline you must submit the work you have completed to date so that if necessary, it can form the assessment.
Where this is the case and you are submitting work by the original deadline, please ensure you include the words EC Pending in the file name submitted. This will inform the marker that this is your work in progress and that there will be another piece of work submitted if your extension is approved. You are then recommended to continue working on your assignment to take full advantage of any additional time.
