Choose by the scores you have
For NSW HSC marks, start with UAC ATAR Compass because UAC has the historical scaling statistics used for NSW. For raw VCE study scores, check the calculator’s scaling year and whether its output is an ATAR or a course selection rank.
If you already have scaled VCE scores, use the historical VCE aggregate lookup to see how they map to VTAC’s 2025 table. For ACT BSSS course scores, see the standard ACT aggregate example.
Check the admissions authority or institution for your official result, course prerequisites and selection adjustments.
