Dude...
You have pretty bad subjects in terms of scaling; and all your ranks are in the lower half.
From my experiences, your looking at a mid 50. Sorry to dissapoint.
Ok im supposed to answer but im not going to (dont know how to work the latex crap )
But just wanted to say : These questions are like Harder 3unti Q's , super awesome, I might add :)
I hate bumping up old threads
But I absolutely can't stop rofling at the massive argument that ensued over the difficulty of a maths paper !
Now, in the spirit of bumping old threads, I'd like to add an opinion.
CSSA 2009 4unit trial = ON Par with HSC standards.
(If you bash me...
To the OP, not to demoralize you man but if you really want this 80 ATAR you honestly shouldnt be banking on scaling- your marks are pretty low. That being said; I still reckon there's some hope.
Math 90 --- > 80 hsc exam mark
Eng 80 ----- > 67 hsc exam mark
Musix 1 40 --- >30ish/50 exam...
