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 topic labels and skills are analytical classifications checked against official questions, syllabi and NESA mapping grids. Each leaf mark allocation is counted once; mixed-topic items retain one allocation. Historical printed-mark shares describe the selected source corpus, including printed alternatives, and are not probabilities for 2026. Selective examiner-advice paraphrases retain the published question or section scope; source links provide the full guidance. The written external examination is indexed. School depth studies are not additional external-paper questions.

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: Investigating Science 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.
