IGCSE Computer Science 0478 is the Cambridge IGCSE Computer Science syllabus. It covers computer systems, programming (often in a chosen language), algorithms, and data. It is one of the most searched IGCSE subjects for students interested in tech and computing degrees.

IGCSE Computer Science 0478 at a Glance

• Theory and practical – Paper 1 (theory) and Paper 2 (problem-solving and programming).
• Topics – Hardware, software, data representation, networks, algorithms, programming concepts.
• Programming – Pseudocode and/or a high-level language; check your syllabus for the exact requirement.

Revision should cover theory (definitions, binary, logic) and practical (tracing code, writing algorithms, debugging).

Revision Tips for IGCSE Computer Science 0478

• Practise pseudocode and code – Trace programs and write small programs under exam conditions.
• Learn binary, hexadecimal, and logic gates – These appear regularly.
• Understand algorithms – Sorting, searching, and basic data structures.
• Use past papers for both theory and programming-style questions.

How Computer Science 0478 Is Assessed and Common Mistakes

The syllabus is assessed with Paper 1 (theory) and Paper 2 (problem-solving and programming). Binary, hexadecimal, logic gates, algorithms (sorting, searching), and programming (pseudocode and/or a high-level language) appear regularly. Common mistakes: Tracing errors in code (practise step-by-step tracing and check loops and conditions); wrong binary/hex conversion (double-check place values); incomplete algorithm descriptions (state inputs, outputs, and steps clearly); ignoring the mark scheme for theory (learn the exact wording that gets marks for definitions and explanations).
