I'd be really, really hesitant about sending such a long email. What are you saying in it?
It's exactly 641 words now. Basically Monash has accidentally (deliberately) made the procedure for exam complaints and grievances very obscure, so I have no idea how it actually works outside of the following page, which legit suggests complaining via post:
https://www.monash.edu/exams/contacts/exam-grievancesSo I'm emailing the chief examiners first because (1) I want to make sure they're aware of exactly how much of a joke the exam timetable the uni has given them is and (2) it seems to me like I'm more likely to get a good result if I work with the chief examiners rather than behind their backs. Therefore I'm just explaining my position - and why they should support it - as thoroughly as possible. So mostly I'm just going over the relevant policies that do and don't apply in this situation, what I want to achieve, why I'm emailing them and why they should help me out. And for brevity I just put a literal list of common sense reasons why it's an unfair schedule at the foot of the email. I also don't want to come across as combative, for obvious reasons.
I guess the email could just be
"Hey A and B,
I'm going to complain to the Examination Services manager about this timetable because it's unfair and your two units are affected by it. It would be great if I had the chief examiners for both units agree with me in this respect. Please support me by agreeing that it's unfair.
Regards,
Achre"
But that seems glib lol
