QCE subject revision
QCE Chemistry revision from real past papers
Chemistry splits its demands: precise definitions and trends on one hand, multi-step calculations across equilibrium, acids and electrochemistry on the other — plus a whole organic pathway map to hold in memory.
No card required, no auto-charge.
What's in the QCE Chemistry external exam
- The external examination contributes 50% of your final subject result.
- Two papers, sat in the end-of-year external assessment block.
- Paper 1 includes multiple choice and short response; Paper 2 is short response.
- Marks hinge on chemical reasoning shown in working — balanced equations, states and sensible significant figures, not just final answers.
The authoritative source on exam structure is always the current QCAA syllabus and assessment specifications — check them for the fine print, and treat this page as a practical summary.
Practise the real questions, one at a time
Queensland publishes its external assessment papers under a Creative Commons (CC BY 4.0) licence, which lets us do something PDFs can't: break real QCAA Chemistry exam questions down individually, map each to the syllabus subject matter, and put them into a practice loop with examiner-style solutions. You attempt before anything is revealed, self-mark against the marking points, and tag why any marks were lost so the next session targets it.
The calculation half of Chemistry is drilled like maths: multi-mark solutions unfold step by step so you commit to the next move before seeing it, and handwritten working can be photographed in via a QR code. The recall half — definitions, trends, reagents and pathways — runs on spaced-repetition flashcards per knowledge point, so the organic map stays producible on exam day, not just familiar.
A daily loop, scheduled by memory science
Each day the app composes one finishable session: quick recall first, then the reviews your memory is about to drop (scheduled by FSRS spaced repetition), then past-exam questions on your weakest knowledge points. As your exam date approaches, review gaps compress so nothing is scheduled past exam day. The technique itself is free — our evidence-based revision guide explains it with citations.
Sit full papers under exam conditions
Knowing the content and performing in the exam are different skills. Sit full past papers as one piece with reading time, writing time and deferred marking, or build your own practice paper from mapped questions by topic. The timed sits guide shows how a sit runs.
Know where you stand
Every knowledge point is colour-coded by mastery on the subject heatmap, and your exam-readiness forecast gives a likely-score range built from coverage, accuracy and recency. It's a compass, not a promise: it guides where to focus, it doesn't guarantee a grade.
Topics covered
- Chemical equilibrium systems, including Le Châtelier's principle and equilibrium constants
- Acids and bases, including pH, Ka and titration curves
- Redox reactions, including galvanic and electrolytic cells
- Structure of organic compounds, including IUPAC nomenclature and isomerism
- Organic reactions and reaction pathways
- Analytical techniques, including mass and infrared spectrometry
- Chemical synthesis and design, including polymers and biomolecules
Coverage is mapped to the QCAA syllabus at subject-matter level, and the heatmap shows exactly which points you've practised.
Pricing

Common questions
Which Chemistry papers are included?
Questions are drawn from official QCAA Chemistry external assessment papers, broken down question by question and mapped to the syllabus subject matter. Inside the app you can also regroup them and sit a paper as one timed piece.
Are calculation questions self-marked too?
Yes — every solution is broken into examiner-style marking points, so you award marks step by step and tag exactly where a calculation went wrong: the concept, the setup or a careless slip. That gap log feeds what the daily loop schedules next.
