How marks and question types are counted

All printed alternatives are counted in these historical shares; candidates follow the paper’s instructions to choose which questions to answer. Mixed-topic items are kept together, and each indexed question contributes its marks once.

ATARMAxxing labels and skill groupings are analysis checked against official NESA mapping grids. A leaf row is counted once; mixed topics retain one shared mark allocation. Examiner advice keeps its published question or section scope. Historical printed-mark shares describe the selected source stratum and corpus; they are not probabilities for 2026. The new 2025 syllabus is first examined in 2029. These records describe the 2017 course.

Use these patterns alongside your own lost marks to choose practice. Keep covering the full syllabus: repeated topics are not guaranteed to appear again.

Official sources and how this analysis works

Classification: Chemistry Stage 6 (2017), applicable to HSC 2026. Each question is counted at the separately marked subpart level. The source questions and stimuli remain in the authority's original documents.
