Key examiner messages
Top priorities from the principal examiner before you revise
Success in this suite is heavily dictated by a candidate's fluency in handling Matter (models and explanations)—which covers material under stress, pressure, and thermal physics, accounting for nearly 60 marks across the papers.
Students who maintained a clear methodology under pressure secured easy marks on Hooke's Law and spring constant calculations.
Conversely, significant marks were lost in the following areas:

Command word playbook
How to match each command word to the expected response style
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 “State” questions.
Match the expected response style for “Complete” questions.
Apply knowledge to an unfamiliar context; concise, practical points score best.
Match the expected response style for “Estimate” questions.
Match the expected response style for “Sketch” questions.
