Hey, I just have a question to pose to you all, I hope somebody out there can enlighten me 
Consider this example:
In a cohort of 80 students for a subject, there are 7 people on 100% SAC markings (i.e. they all have 100/100 internal scores). How do VCAA deal with moderating these SAC marks if the 7 people get wildly differing exam marks. For example, 1 student gets 100%, another gets 95% the rest get 80%, what will their moderated SAC marks become? Can they be different for each person, or will they all have to be equal?
sadly, they will be equal [and i take my sources to be correct, though i cannot reveal them]
this is the reason why your teacher MUST rank you. there has been a case with a particular school that had four equal-firsts, and the teacher has placed them equal-firsts [rather than giving a rank], the result was one of them was significantly disadvantaged [this is why you shouldn't have easy SACs, and why MHS have extraordinarily hard ones]
yes, this part DOES suck.
