lol its extenuating circumstances and i used them every year
1st year medical note so i was allowed to resit loads in summer as opposed to resitting the whole year
2nd note to say was not fit for exams so i could resit without being capped
3rd yr knew i failed an exams, ran to docs got a note sayin i was sick before and so they let me pass that module at just 35%
they can be lenient etc or let you retake
