What happened with the exam Paul, if you don't mind me asking?
5/10 on Language Analysis, totally a disaster, because I did really well on the other two essays.
1 - I think it got confused around the issue of teacher discretion. Highest study score "dux" doesn't involve discretion (unless they wrongly fudge the VCAA reporting) but school dux might. I just worry when the terms and discussion become confused because you see people getting the wrong impression of things and starting to freak out based on it.
2 - I'd probably keep that under wraps, if I were you! By doing that your teacher has unfairly disadvantaged any student who got moved down to make room for you, and we've all seen legal action being taken over less (cough, recent law wannabe).
1 - yes, you're right, highest study score dux doesn't require any discretion, but I don't really see why you would care/freak out about being the school dux for a particular subject, not as if that actually counts towards anything anyway, but at my school, dux = highest study score, overall dux = highest ATAR
2 - yeah, it was a bit dodgy because I wasn't the only one I know someone else who had his raw mark entered higher than what it was as well, but for all I know, it could have easily been an error whilst entering the marks, but I don't think that's right that they would make such an error
