Structure unverified
QCE subjects moved to the QCAA 2025 General senior syllabuses in 2025, and 2026 is the first year they are externally assessed. Timing follows the 2026 QCAA timetable: two papers, each 90 minutes plus 5 minutes perusal, sat in separate sessions on the same day. This mock runs both as one sitting. We could not confirm the 2026 external assessment format and mark allocation from QCAA documents, so this mock follows the shape of recent past papers. Check the QCAA syllabus and your school's advice before treating it as a dress rehearsal. Its question styles come from past papers set on the 2019 QCAA syllabus; the 2025 syllabus applies from the 2026 external assessments.
