Command word playbook
How to match each command word to the expected response style
Give reasons and link mechanism to outcome; each point needs a because/so chain.
State features in sequence or list observable properties — do not explain causes unless asked.
Show formula, substitution, and unit; method marks need visible working.
Apply knowledge to an unfamiliar context; concise, practical points score best.
Weigh arguments for and against with evidence; end with a supported judgement.
Match the expected response style for “Define” questions.
