2025 data · About these estimates

Points pair marks at the same cohort percentiles in the 2025 report. They do not track individual students or guarantee that an entered mark scales to the plotted value. Lines are a visual guide. Scaling changes each year. These are Year 12 results, not predictions for Year 11.
