IGCSE Computer Science 0478 Past Papers

How to identify the paper, session and variant

Cambridge papers are named from the syllabus code, the session, the type of document and the paper number. A file such as 0478_s23_qp_12 reads as: syllabus 0478, May/June 2023, question paper, paper 1 variant 2.

In Cambridge file names m means February/March, s means May/June and w means October/November, followed by the two-digit year.

The two digits after the document type are the paper number and the variant: 12 is paper 1, variant 2. Variants are different versions of the same paper set to the same standard, so use the one that matches your entry or practise several.

Attempt a paper under timed conditions

Choose a paper that matches your course, set the time allowed on the front page, and work without notes. Stopping early to look something up hides the gaps you are trying to find.

Write algorithms and pseudocode in the style the syllabus uses, and trace them with a simple table of values.

Practise short explanations of terms in your own words, as well as longer programming or design questions.

Answer theory questions briefly and keep time for the longer algorithm or programming tasks, which carry more marks.

Checking your answers

No mark schemes have been added for Computer Science yet. Until they are, ask your teacher to check your work or look for the matching mark scheme on CAIE's website.

Compare your algorithm with the accepted alternatives; for programming questions, several correct solutions may earn full marks.

Typical slips are an off-by-one error in a loop, pseudocode that does not follow the expected style, and explanations that name a term without defining it.

Keep an error log and plan your revision

After each paper, write down every lost mark in a log. Record whether marks were lost for logic errors, syntax or pseudocode style, unclear explanations or misread requirements.

Then turn the log into a short weekly plan: choose two or three topics, revise them from your notes, and test them with fresh questions. Spread the papers you have across several weeks instead of attempting them all at once.

A good week pairs one paper with a practical session where you run the algorithms you wrote, then a quick revision of the definitions you missed.

Practise by area such as data representation, networks, databases or programming, and revisit weak areas with fresh questions.

Check that the syllabus version matches

Check that 0478 is the code on your course outline and which examination years your syllabus version covers, because content and paper structure can change between syllabus versions.

How do I find the correct IGCSE Computer Science 0478 paper?

Check three things on the paper: the session and year, the paper number, and the variant or level when there is one. Cambridge papers are named from the syllabus code, the session, the type of document and the paper number. A file such as 0478_s23_qp_12 reads as: syllabus 0478, May/June 2023, question paper, paper 1 variant 2.

Which 0478 syllabus version should I choose?

Check that 0478 is the code on your course outline and which examination years your syllabus version covers, because content and paper structure can change between syllabus versions.

Where can I find the matching mark scheme?

No mark schemes have been added for this subject yet. Check CAIE's website or ask your teacher, and see the list above as new files are added.

Are all IGCSE Computer Science 0478 past papers on this page?

No. This page lists only the files that have been added so far, and some sessions may be missing. For the full official list, use CAIE's own website.

What should I do after marking a Computer Science paper?

Record whether marks were lost for logic errors, syntax or pseudocode style, unclear explanations or misread requirements. Then revise the topics behind those marks and test them again with fresh questions.

Are these files endorsed by CAIE?

No. The papers are published by Cambridge Assessment International Education. Trinity Tutors is an independent tutoring service and is not endorsed by or affiliated with the board, and it cannot promise any particular grade or result.

Should I test my Computer Science answers on a computer?

Where a question asks for code, running it is the best check. For written answers, compare your wording with the mark scheme.

Can a tutor help me with Computer Science?

You can browse a Computer Science tutor or contact us with the board, level and topics that cost you marks, and we will say honestly whether we have a suitable tutor.
