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.

Topic and skill labels are ATARMAxxing analysis, not official question wording. Historical shares use all indexed printed marks and are not future probabilities. Multiple-choice correct percentages use the published official key; incorrect percentages sum the other published options and exclude omissions. Revised 2026 syllabus conditions apply. © State of Queensland (QCAA), source publications linked under their stated CC BY 4.0 terms and exceptions.

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: Historical papers: 2019 General syllabus; current core-content mapping: 2025 syllabus v1.3 for 2026 assessment. Each question is counted at the separately marked subpart level. The source questions and stimuli remain in the authority's original documents.
