Hello,
If you absolutely ace the GAT of the Math/Science sections ie. getting standardised scores of 46+, and did not score well in the first Method SAC due to the bias' of teachers; may happen to more SACs[deducting marks for errors whilst not deducting for other people] and later get an A+ in the End of Year exams (you get 99% on both exams), will you be able to get a higher SS than your peers who are ranked 1st and you are ranked 9th for example?
Or in other words;
You get 100% basically in the Exam but ranked in the middle of a weak cohort, and ace the GAT, does VCAA pick up a single student which is oddly marked internally. ie, wow.. 46+ in GAT of the Math/Sci section, only an A for unit 3 and 4 SAC's but strangely 100 % on the exams;A+ in the exams.
