IGCSE Sciences - Co-Ordinated (0973) — real past-paper questions, marked by AI
0973 reports Cambridge Co-ordinated Sciences on the 9-1 grade scale, spanning biology, chemistry and physics content across Papers 1 and 2 multiple choice, Papers 3 and 4 theory, and Papers 5 and 6 for practical work. Practical skills sits at the top of the topic table, alongside atomic structure, enzymes and radioactivity, so a single revision block genuinely crosses all three sciences.
This hub carries 2,151 real 0973 questions from 42 papers set between 2023 and 2025. Photosynthesis, forces, and electrolysis all rank among the most-examined topics too, giving a clear map of where the marking points cluster across biology, chemistry and physics. Write your answer and the AI examiner marks it point by point against the real Cambridge scheme, showing which idea earned the mark whichever of the three sciences the question draws on.
Work through one topic at a time, then sit full timed papers that mix all three sciences the way the real exam does. Free, with no signup required.

Frequently asked questions
Which 0973 papers and years are covered?
Every May–June and October–November session from 2023 to 2025 — 42 papers across Papers 1 to 6, with every variant included.
Which code am I — is 0973 the same as 0654?
0973 is the 9-1 graded version of IGCSE Co-ordinated Sciences (0654): the same content and exam style, reported on the 9-1 grade scale rather than A*-G.
How does the AI marking work across three sciences?
The AI examiner checks each answer against the real Cambridge mark scheme for that specific question, awarding marks point by point regardless of which of the three sciences the question comes from.
What do Papers 1 to 6 mean in 0973?
Papers 1 and 2 are multiple choice, Papers 3 and 4 are theory papers, and Papers 5 and 6 cover practical work, either in the lab or as 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.
