0478 Paper Components Set in 2022

In 2022, Cambridge set 6 distinct paper variants across the 3 sessions of IGCSE Computer Science. All variants of a given paper test the same syllabus content and are graded to the same standard — only the specific questions differ.

Why multiple variants? Cambridge sets two or three versions of every paper to manage exam security across global time zones. A paper sat at 9am local time in Singapore would finish before the same paper started in the UK — without separate variants, leaked questions could spread eastward before Western candidates sat down. Each variant is timed and assigned to a specific administrative zone so candidates in different time zones never see the same questions.

How to read the variant code: the two-digit number after the slash is paper-number + variant-number. So 0478/12 is Paper 1, Variant 2; 0478/41 is Paper 4, Variant 1. Your school's administrative zone determines which variant you sit — Variant 1 typically goes to schools in Africa, Europe and the Middle East; Variant 2 to South Asia (India, Pakistan, Bangladesh, Sri Lanka) and parts of South-East Asia; Variant 3 to East Asia and the Pacific.

2022 variant pattern: the Feb/March series — where offered — only sets Variant 2 papers because it serves a single administrative zone; May/June and October/November sessions typically set all available variants. February-March 2022 set variants 12, 22; May-June 2022 set variants 11, 12, 13, 21, 22, 23; October-November 2022 set variants 11, 12, 13, 21, 22, 23.

Note: Times shown are the official Cambridge writing time and do not include the 5 minutes of reading time given before most papers begin. Your tier (Core or Extended, where the subject offers tiering) determines which papers you sit.

When are Cambridge IGCSE Computer Science exams held?

Cambridge IGCSE Computer Science (0478) is offered in up to three sessions each year: Feb/March (limited to certain regions, mainly India), May/June (the main worldwide session), and October/November. Most candidates sit either the May/June or October/November series. The 2022 papers on this page cover all 3 sessions that ran in 2022.

What's the difference between Paper variants like 11, 12 and 13?
Cambridge produces several variant papers from each paper to manage exam logistics across global time zones. Papers 11, 12 and 13 are three different versions of Paper 1; papers 21, 22 and 23 are three versions of Paper 2; and so on. Your school assigns you to one version based on your administrative zone. Cambridge generally writes a distinct question set for each version of the paper, and each variant paper usually covers a different mix of syllabus topics — the topic mix on the version you sit may differ noticeably from another candidate's. Cambridge calibrates all variant papers to equivalent overall difficulty and sets a separate grade threshold for each one. For thorough revision, rotate through different versions when you practise past papers — each one covers a different slice of the syllabus.
Is one paper variant harder than another?
No version of the paper is systematically "easier" or "harder" than the others. Cambridge writes every variant paper to the same overall difficulty target, and if small differences emerge during a session they're absorbed by per-paper grade thresholds set after marking — a slightly harder version typically gets a slightly lower threshold, so candidates end up worth the same grade for the same level of performance. You can't choose your variant paper anyway (your school's administrative zone determines it). If a friend's paper looks "easier" than yours, it's usually because the specific topic mix happened to hit their strengths rather than the paper being genuinely lighter.
Are mark schemes and examiner reports free to download?
Yes — and LumiExams makes them easy to find. The 0478 question papers (QP), mark schemes (MS), examiner reports (ER) and grade thresholds (GT) are all © Cambridge Assessment International Education, published after each session as free educational materials. LumiExams does not own these documents — we organise the official Cambridge PDFs by year and session so you can study with the same materials your teachers and exam officers reference, and we link directly to each file. For official syllabuses, registration and assessment policy, refer to cambridgeinternational.org.
How should I use the 2022 Computer Science papers for revision?

Work through one full paper under timed exam conditions, mark it with the official mark scheme, then read the examiner report for that session. The examiner report highlights the questions students typically got wrong and explains why — that's where the highest-leverage revision wins are. Cambridge updates each syllabus in roughly 3-year cycles, so the 2022 papers reflect the syllabus version that was active in 2022. Before relying on these for the year you're sitting, confirm the active syllabus on Cambridge International's official 0478 page.
