Cambridge IGCSE ICT 0417: Command words and keywords

Cambridge IGCSE Information and Communication Technology (0417) uses the standard Cambridge command words. Examiner reports emphasise that evaluation requires detailed reasoned responses weighing advantages and disadvantages, and that analysis and discussion need detailed responses rather than short bullet points. Use correct technical terms rather than brand names.

Command words in ICT 0417

Command word	What to do in ICT	Common mistake
State	Short answer; one point per mark	Overwriting

Critical: Evaluation and discussion

Evaluation requires judging quality or importance with detailed reasoned responses that weigh advantages and disadvantages. Analysis and discussion require detailed responses—not short or bullet-pointed answers. Structure your answer with clear development.
