Yeah, i wouldn't either, gotta be at least a D i would think.
Here on the other hand...I'm at like 40% of normal, if it were to end here i'd probably be close to an F or D-. But i'm pretty hopeful on cracking 20...sad times.
Significantly better here than 22-23 and 19-20 but far worse than 18-19 and 15-16
