Mitigating circumstances

It will almost certainly be enough for the claim to be accepted, yes - but the mitigation outcome is not pre-determined (usually, anyway) and so if I were you, I'd get involved in this your academic advisor and/or someone from your department who sits on the examination board. This is because they can then put across your preferred outcome as an option - the way this usually works is that examination boards accept the mitigation claim and then they suggest a route forward that will be most beneficial to your grade outcome. If you aren't gonna sit the exams then they will need to have this made explicit in advance. Get onto this ASAP.

It says on their policy that the most likely route is to sit the exams in the next exam period. Only in exceptional circumstances it may change. Even if I sit the exam (only if I don't have the outcome by then), they'd void the result and let me sit it in the next exam period. But I'll still let them know of my preferred outcome. Thanks.
