One scaling calculator for every HSC and VCE subject
Every Year 12 subject is scaled before it counts towards your ATAR. This tool brings all 31 major HSC and VCE subjects into one place. Pick your subject, enter your result, and see the scaled score the official report points to.
HSC and VCE scale in different ways, and this calculator handles both. For an HSC subject, you enter your exam mark out of 100 and see your scaled mark out of 50. For a VCE subject, you enter your study score out of 50 and see your scaled study score, which can sit above 50 for the strongest-scaling subjects.
Why subjects scale up or down
Scaling is not a measure of how hard a subject is. It reflects how the students in that subject performed across all their other subjects. Subjects taken by very strong cohorts scale up. Subjects taken by broader cohorts scale down. Your rank within the subject never changes.
That means a strong score in a subject you are good at almost always beats a weak score in a high-scaling one. Choose subjects you can do well in, not subjects you think will scale.
Want more detail on one subject?
Each subject also has its own calculator with a full scaling table and percentile context. Browse all of them on the HSC scaling calculators and VCE scaling calculators pages, or read how it all works in our methodology. To turn your scaled scores into a full ATAR, use your state calculator from the ATAR calculators hub.
