IGCSE Computer Science (0984) — real past-paper questions, marked by AI
IGCSE Computer Science (0984) is the 9-1 graded version of 0478 — the same two written papers, the same trace tables and pseudocode questions, marked 9 to 1 rather than A* to G. Write, state, explain: the command words demand exact logic, whether you are naming a hardware component or fixing a broken algorithm.
The hub holds 413 real 0984 questions from 16 papers set between 2023 and 2025. Hardware primary storage and databases data types share the top of the topic table, with data representation, output devices and CPU architecture also examined, alongside encryption under security. Type your answer, trace table or corrected pseudocode, and the AI examiner marks it instantly against the real Cambridge mark scheme, checking your logic against the scheme rather than just your wording.
Drill hardware and data representation questions first, since they reward precise terminology, then try a timed paper. It is free, with no signup needed.

Frequently asked questions
Which 0984 papers and years are covered?
Every May–June and October–November session from 2023 to 2025 — 16 papers across Paper 1 and Paper 2 and their variants.
What is the difference between 0984 and 0478?
0984 is the 9-1 graded version of IGCSE Computer Science, graded 9 to 1 rather than A* to G, with the same course content and exam style as 0478. Check which code your school registered you for.
How does the AI marking work for trace tables and pseudocode?
You type out your trace table values or corrected pseudocode, and an AI examiner checks each step against the official Cambridge mark scheme, confirming exactly where your logic matched or missed it.
How should I revise Computer Science theory with past papers?
Work through hardware, data representation and security questions by topic first, then move to full timed papers to build speed and accuracy together.
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?
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.
