IGCSE Chemistry (0971) — real past-paper questions, marked by AI
0971 reports Cambridge IGCSE Chemistry on the 9-1 grade scale, but the exam itself still rewards the same precision as the A*-G version: the right ion, the balanced equation, the observation you would actually see. Papers 1 and 2 are multiple choice at Core and Extended tier, Papers 3 and 4 theory papers, Paper 5 the practical test and Paper 6 the alternative to practical.
This hub carries 1,744 real 0971 questions from 44 papers set between 2023 and 2025. The Periodic Table leads the topic count, with states of matter, chemical bonding, stoichiometry and electrochemistry all among the most-examined areas. Write your answer and the AI examiner marks it instantly against the real Cambridge scheme, flagging whether you named the correct product, ion or reagent rather than describing a reaction only in general terms.
Sweep stoichiometry or organic chemistry across the full range, then sit a timed variant. Free, with no signup required.

How does the AI marking work for chemistry answers?
The AI examiner checks your typed answer against the real Cambridge mark scheme for that exact question, awarding each marking point and showing the accepted term or equation you needed.
What do Papers 1 to 6 mean in 0971?
Papers 1 and 2 are multiple choice at Core and Extended tier, Papers 3 and 4 are theory papers, Paper 5 is the practical test, and Paper 6 is the alternative to practical.
Is it really free?
Yes — every question, mark scheme and AI marking run is free, with no signup and no card details.
Are these official Cambridge papers?
The questions are transcribed from real Cambridge papers and marked against the real mark schemes, which remain © Cambridge International. Cambridge Papers is an independent study tool, not affiliated with or endorsed by Cambridge.
