If you're ranked nth for sacs, then the nth best exam score in your cohort becomes your sac score for that subject.
Is this confirmed? Because my friends brother finished 2nd in sacs for methods and got A+ on both exams (rank 1 also got A+) but only got an A for sac marks.
Also, does any one know if this is true? My teacher was saying the other day that if you finished with a pretty average rank (say 20th) but then do much better than a lot of those above you then VCAA may move your rank up?
I thought it was true, but confirmation would be nice?
and yeah, im fairly sure that vcaa can amend sac marks if they dont match..
I think that your rank in your cohort cannot change under normal circumstances, however I do not believe that every exam mark becomes somebody's final SAC mark. The reason for this is because if this were true, the grade distributions for SACs and exams should be rougly equal (e.g. if 10% of the state gets above 85% on an exam, 10% of the state (not necessarily the same 10%) should get above 85% on their SACs).
However, looking at the grade distributions, final SAC scores show a clear majority of higher scores, whereas exam marks are reasonably normally distributed. Indeed, from the VCAA's own website,
http://www.vcaa.vic.edu.au/vce/exams/statisticalmoderation/statmod.html, you will notice that the exam scores did not exactly become the moderated SAC scores, but the ranking was still preserved.
