HSC Chemistry Past Papers 2026
Where to find official HSC Chemistry past papers, what each module tests, and how to turn a marked paper into a targeted revision plan.
NESA publishes official past HSC Chemistry exam papers, marking guidelines and examiner feedback for free on the NESA website, going back several years under the current (2017) syllabus. Chemistry papers test calculation skills and reaction mechanisms as much as recall, so marking your own attempt against NESA’s guidelines is the fastest way to find where working-out, not just final answers, is losing marks. This page explains what each module covers, then links you into Revizi’s syllabus-mapped practice for the modules a past paper shows you’re weak on.

Past Paper: The HSC Chemistry exam is 100 marks in 3 hours: Section I is 20 multiple-choice questions (20 marks), and Section II is a combined short and extended responses section (80 marks) drawn from Modules 5–8, including calculations — NESA doesn’t publish a fixed sub-split of that 80 marks. NESA’s official past papers and marking guidelines show exactly how partial credit is awarded for working-out — review these line by line, not just the final mark.

Frequently Asked Questions
Where can I find official HSC Chemistry past papers?
NESA publishes official past HSC Chemistry exam papers, marking guidelines and examiner feedback for free on its website under HSC exam papers, for several years under the current syllabus.
Does Revizi host official NESA past papers?
No. NESA’s past papers are copyrighted and hosted on the NESA website. Revizi provides original, syllabus-mapped practice questions for each Chemistry module — use both resources together: NESA papers for realistic full-exam and calculation practice, Revizi for targeted topic revision.
How many years of Chemistry past papers should I do?
Most students get the most value from the last 3–4 years under the current (2017) syllabus. Do them under timed, calculator-permitted conditions, mark against the official guidelines, then use Revizi to revise whichever modules cost you the most marks.
What is the format of the HSC Chemistry exam?
The HSC Chemistry exam is 100 marks in 3 hours: Section I is 20 multiple-choice questions (20 marks), and Section II is a combined short and extended responses section (80 marks), including calculation questions. NESA does not publish a fixed sub-split of that 80 marks.
