Find official questions, understand lost marks and choose what to practise next.
Historical evidence and practice priorities. Future exam questions are not guaranteed. Independent of QCAA.
Common internal assessment (CIA), not a General-subject external examination. Indexes 33 whole questions from the 2023–2025 Phase 1 CIA papers (50 marks each). Other phases are linked through the official archive but are not pooled. All items link to their question and marking-guide pages; no official item-performance statistics were verified. Showing 6 sample entries; trend percentages use this sample only. Official result percentages describe the published exam cohort.

Find your next question
Choose a topic, open the official question, then check your answer against examiner feedback.
Official averages are unavailable for these entries. Fewer marks means a smaller question, not an easier question.

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.
Current CIA scope is Unit 3 calculations, measurement, scales/plans/models and probability/relative frequencies. Older statistics items now belong to Unit 4: labelled historical and excluded from current CIA recommendations. Probability has no observations in this selected older series; absence is not evidence of low 2026 importance. Topics are manually mapped from each parent question. Historical shares use all printed parent marks within a year, including clearly labelled historical items, and are not forecasts.
Use these patterns alongside your own lost marks to choose practice. Keep covering the full syllabus: repeated topics are not guaranteed to appear again.
