How this estimate is produced

We place your reported mark in the 2025 course distribution, read the matching scaled mark, and apply the TISC counting rule. Modelled on UAC’s course scaling distributions. WACE course cohorts differ, so results are indicative.

Confidence

Indicative estimate: the counting rules are local, but the scaling distributions are national reference data. Expect the official result to differ by a few points.
