I got special consideration for my mid-sem exam (worth 15%), for which I received an email prompting me to request the unit coordinator for a replacement exam by including my Spec-Con application number.
So I thought till I sent an email, I wouldn’t get my replacement exam. But then I received a separate email with my replacement exam date which I completely missed. So in conclusion I messed up, and missed my replacement exam.

How does the Better Mark Principle work in a situation like this, because my final is worth 60%. Or am I just screwed. Thanks guys
