How CtrlAltRevise works

Choose Cambridge IGCSE Computer Science 0478 or 0984 (9–1). The 0984 roadmap currently projects the verified 0478 content set; equivalence is still being checked. AS & A Level 9618 is not yet available.

Read short notes and worked examples, then complete the lesson quiz. The notes introduce the ideas before asking you to use them.

Use questions matched to the lesson where available, or open a topic practice set when you have covered the relevant material. Check the supplied answers and explanations.

Use the built-in pseudocode workspace to write, syntax-check, and interactively run Cambridge pseudocode. Use it to test small programs and check your reasoning.

Your dashboard shows progress across every topic and objective. A spaced-repetition review queue surfaces topics that need more practice before the exam.
