Core ideas you must master

Area	What it means	How the exam uses it
Key terms	Subject vocabulary for Validation And Verification	Define, state, identify
Methods	Standard procedures and skills	Calculate, explain, describe
Application	Use knowledge in new contexts	Analyse, evaluate, discuss
Exam technique	Command words and mark allocation	Show working; label diagrams

How to revise Validation And Verification — step by step

1. Read the subtopic page — note definitions and worked examples.
2. Summarise key terms on one revision sheet.
3. Practise short questions before long structured answers.
4. Use the quiz to find gaps — Validation And Verification quiz.
5. Review mistakes and re-test weak areas.

Command words that matter

Command word	What the question wants
State / Name	Short factual answer
Describe	Say what happens; sequence or features
Explain	Give reasons; cause and effect
Calculate / Work out	Show method; include units if needed
Analyse / Evaluate	Break down; judge with evidence
Discuss	Range of points; balanced conclusion

Worked exam-style stems

1. “Explain …” — Define the key term, give two linked reasons, use subject vocabulary. Reward: knowledge + development.
2. “Describe …” — Sequence main steps or features without unnecessary opinion. Reward: accuracy + completeness.
3. “Evaluate …” — Present advantages and limitations; conclude with a justified judgement. Reward: balance + evidence.

Practise these on the Validation And Verification subtopic page and Validation And Verification quiz.

Common mistakes students make

• Vague definitions that do not use correct terminology.
• Ignoring command words — describing when asked to explain.
• Missing units or labels in calculations and diagrams.
• Skipping the subtopic quiz before attempting full papers.
• Not linking Validation And Verification to the wider topic Algorithm Design And Problem Solving.
