Key examiner messages
Top priorities from the principal examiner before you revise
High scoring was concentrated in the early parts of questions focusing on atomic models, hydrocarbon structures, and basic separation techniques.
However, significant marks were lost in the following areas:

Command word playbook
How to match each command word to the expected response style
Match the expected response style for “Name” questions.
Show formula, substitution, and unit; method marks need visible working.
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.
Match the expected response style for “Draw” questions.
