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.
2024–2025 complete printed question corpus: 43 questions, separately marked parts or printed alternatives. Historical tasks cover data exchange, algorithms, security and interfaces. The current syllabus adds explicit APIs and revised conditions. Both subject reports are evidenced by selected official indexed excerpts because complete PDFs exceeded the reader limit. Showing 6 sample entries; trend percentages use this sample only. Official result percentages describe the published exam cohort.
Free sample: progress lasts for this visit.
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. 4 questions have sourced incorrect-answer percentages. 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.
Original ATARMAxxing indexing labels are analysis, not official question wording. Historical marks do not predict future probability. Multiple-topic rows may contribute to multiple topics. Missing numerical results remain unavailable. © State of Queensland (QCAA); linked publications retain their CC BY 4.0 terms and stated 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.
