Exams were cancelled and prelim grades weren't great ):

I'm in 6th form and applied to uni, but now without my final exams they'll use my predicted grades, which weren't really good because my gran was going through a difficult time and now... Been working really hard for the exams but they're now cancelled )))): I've applied for extenuating circumstances at the uni I want to go to, but I'm really scared they won't accept me
