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.
Independent topic and skill analysis of linked SACE Board examinations. Historical question counts and printed marks describe the indexed sources, not 2026 probabilities. Optional prompts are separate records. Unknown item marks and performance remain null. Copyright remains with the SACE Board and credited source owners; full question wording is not republished. From 2026 the multiple-choice section reduces from 15 to 10 questions, so historical section shares are not the current blueprint.
Use these patterns alongside your own lost marks to choose practice. Keep covering the full syllabus: repeated topics are not guaranteed to appear again.
