Hi, New to VCE
what it means by ‘how your sacs scale’
Curious to know
A 90% at one school isn't the same as A 90% at another schools because different schools do different sacs. To make sac marks fair between schools, vcaa disregards the percentage you get on your sacs and instead uses your rank within your cohort and your cohorts exam performance to scale your sac.
Eg. If one cohort of 4 people gets exam scores of 90%, 80%, 70%, and 60% and another cohort of 4 people gets exam scores of 70%, 50%, 30%, and 10% then a person who is rank 2 in the first cohort will have their sacs scale to around 80% whereas a person who is rank 2 in the second cohort will have their sacs scale to around 50% - and this will be true regardless of whether they have the same % mark on their sacs. (The difference isn't usually that drastic though because cohorts are larger than 4 people). There's more on how it works
here under the heading "sac moderation"
SACS: 97 (above avg cohort)
Exam 1: 38-39/40
Exam 2: 73-76/80
44-47
