How English Extension 2 scaled in 2024

This subject scales up significantly. The average student in this course outperformed the average student across all senior secondary subjects, so the scaling process boosts the cohort's marks. A solid raw mark in this subject is worth more in scaled terms than the same raw mark in most other subjects.

For English Extension 2 specifically, the scaled distribution runs from P25 of 31.4 to P90 of 44.4 — a spread of 13.0 scaled points between the bottom and top quartiles of the cohort. That spread is the practical room for movement within this subject: a student who moves from the bottom quartile of English Extension 2 to the top decile gains roughly 13 scaled points per unit, which is significant when multiplied across 2 units toward the ATAR aggregate.

The gap between HSC mark and scaled mark at P90 was -3.6. That gap is negative — top-performing English Extension 2 students were scaled down in 2024. This is what scaling actually does: it's not a percentage multiplier; it's a candidature-position adjustment.

Tutor rate context for English Extension 2

Subject complexity classification: high — small qualified-tutor pool. Based on our subject-complexity model, this subject typically carries a +22% adjustment to the base AU tutor rate band — partly because of the qualified-tutor pool size, partly because of subject-specific marking and exam complexity.

How to read the distribution

The HSC mark column shows the raw HSC mark you would have needed to sit at each percentile of the English Extension 2 candidature in 2024. The scaled mark column shows what that performance was worth toward your ATAR aggregate. The two values diverge because scaling reflects the academic strength of the candidature as a whole — it is not a fixed conversion of raw HSC mark to scaled mark.

The same HSC mark can produce a range of scaled marks (because students with that HSC mark may have different positions in the underlying cohort). This is why UAC publishes a distribution rather than a lookup table.

Caveats specific to English Extension 2

• This is 2024 data. UAC recomputes scaling each year — 2025 figures will move if the candidature mix changes.
• The HSC mark on your transcript is the NESA-reported HSC mark (aligned to course standards). The mark used in scaling is the raw HSC mark, which is not reported to students directly.
• For courses with combined candidatures (English Standard / Advanced / Studies share a common scale via the NESA standards-aligned raw marks), UAC's scaling treats the combined group; per-course reporting is for transparency.
• Use the scaling data to understand the system, not as the only input to subject selection. Subject engagement matters more than scaling pattern at every level except perhaps the very top decile.
