What happens between your school rank and your ATAR?
Your HSC mark and your ATAR are two different steps. Here is the useful version — with your own subjects plotted when you calculate.
1 · Your HSC mark
Rank matters. So does your exam.
For most HSC courses, your reported mark combines your aligned exam mark and your moderated school assessment mark equally.
The simple formula
(85 assessment + 80 exam) ÷ 2
= 82.5 HSC mark
A simplified first-place example
1st
You finish first internally
85
Highest exam mark at school
80
This result stays yours
82.5
The two halves averaged
This is a simplified example. NESA moderates the whole school assessment distribution while preserving the school’s rank order — it does not simply swap every student’s mark one-for-one.
2 · Scaling explorer
Doing better changes the scaling story.
Scaling compares course candidatures, but it is not a fixed bonus or penalty. The strongest strategy is still to choose suitable subjects and earn the highest marks you can.

Historical illustration only. UAC recalculates scaling each year and does not report individual scaled marks.
