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 Tree Diagrams subtopic page and Tree Diagrams 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.
