Assessment Boards make their decisions using the same information provided to students about what are acceptable circumstances (and what are not), and what is the necessary evidence, so you are advised to read the guidance carefully before completing and submitting a MC request.
You are strongly advised not to risk completing an assessment of any type if you are experiencing difficulties that would have an adverse impact on your academic performance and would meet the definition of mitigating circumstances. In this situation, by submitting a MC request you are complying with the College’s regulations and are making a conscientious decision to be assessed at a time when your circumstances have improved.
