QCE Chemistry Past Papers 2026
Where to find official QCE Chemistry past external assessment papers, what each unit tests, and how to turn a marked paper into a targeted revision plan.
QCAA publishes official past QCE Chemistry external assessment papers, released under its CC BY 4.0 licence (© State of Queensland (QCAA)), free and public via the link above. Chemistry EAs test calculation technique alongside recall, so marking your own attempt against QCAA’s guide is the fastest way to see where working-out, not just final answers, is losing marks. This page explains what each unit covers, then links you into Revizi’s syllabus-mapped practice for the units a past paper shows you’re weak on.

Frequently Asked Questions
Where can I find official QCE Chemistry past papers?
QCAA publishes official past QCE Chemistry external assessment papers, released under its CC BY 4.0 licence, free and public on its website — see the official link above.
Does Revizi host official QCAA past papers?
Revizi doesn’t reproduce QCAA’s past papers here — get those directly from QCAA using the link above. Revizi provides original, syllabus-mapped practice questions for each Chemistry unit — use both resources together: QCAA papers for realistic full-EA and calculation practice, Revizi for targeted topic revision.
How many years of Chemistry past papers are there?
QCE’s external assessment only began in 2020, so there’s a shorter run of past papers than older curricula — usually 4–5 years available. Do them under timed, calculator-permitted conditions, mark against QCAA’s guide, then use Revizi to revise whichever unit cost you the most marks.
What is the format of the QCE Chemistry external assessment?
A written examination covering Units 3 and 4, contributing 50% of your final subject result, marked against QCAA’s published assessment objectives.
