HSC ATAR Calculator
The HSC is completed over Year 11 (Preliminary) and Year 12 (HSC year), but only your Year 12 HSC marks count for ATAR. Each HSC mark (0-100 per unit) is scaled to account for subject difficulty. UAC sums your best 10 scaled units (including at least 2 of English) to form an aggregate, which is converted to an ATAR — a percentile rank from 0.00 to 99.95.
Score Range
0 – 50
English
Must include at least 2 units of English (any English course)
Aggregation
HSC courses are measured in "units" — most subjects are 2 units, Extension courses are 1 unit each. For your ATAR, UAC counts your best 10 units from Year 12 Board Developed courses, which must include at least 2 units of English. A maximum of 2 units of Category B courses can count. The aggregate of these best 10 scaled units is then converted into your ATAR.
This chart shows the approximate scaled score at a raw midpoint score for each subject. Subjects above the dotted line scale up (harder subjects), below scale down (easier subjects).
Based on approximate scaling data. Actual scaling varies by year and cohort.

Remember: Scoring well in a subject you enjoy will almost always beat scoring poorly in a "better scaling" subject. Choose subjects you're genuinely interested in.
