IGCSE Marine Science (0697) — real past-paper questions, marked by AI
Marine Science questions move between oceanography, ecology and human impact in the space of a single structured paper, expecting you to describe a process — a trophic level, a tectonic boundary — and then suggest its consequence for a named ecosystem. The papers on the hub run as structured and data-response questions rather than essays, so marks are won in short, specific answers.
This hub holds 589 real 0697 questions from 19 papers set between 2023 and 2025. Oceanography leads the topic table, with human impacts on marine ecosystems, marine biodiversity and plate tectonics close behind, alongside food webs and trophic levels further down the list. Type your answer and the AI examiner marks it instantly against the real Cambridge scheme, showing which named process or example you needed rather than a general description of 'pollution' or 'the ocean changing'.
It is a smaller syllabus, so make each session count: sweep oceanography or human-impact questions first, then attempt full papers. Free, with no signup and no card needed.

Frequently asked questions
Which 0697 papers and years are covered?
Every May–June and October–November session from 2023 to 2025 — 19 papers across all three components, with every variant included.
How does the AI marking work for Marine Science answers?
The AI examiner checks your typed answer against the real Cambridge mark scheme for that exact question, crediting each marking point and showing which named process or example the scheme was looking for.
What do the components mean in 0697?
The hub's papers follow a structured, data-response format across the components listed, drawing on oceanography, marine ecosystems and human-impact topics.
Is it really free?
Yes — every question, mark scheme and AI marking run is free, with no signup and no card details.
How should I revise Marine Science with past papers?
Work through one topic at a time — oceanography, then human impacts, then plate tectonics — before sitting full timed papers and using the feedback to add named detail to general answers.
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.
