Key examiner messages

Top priorities from the principal examiner before you revise

1

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.

2

Students who maintained a clear methodology under pressure secured easy marks on Hooke's Law and spring constant calculations.

3

Conversely, significant marks were lost in the following areas:

Command word playbook

How to match each command word to the expected response style

CalculateFrequency: 14

Show formula, substitution, and unit; method marks need visible working.

ExplainFrequency: 12

Give reasons and link mechanism to outcome; each point needs a because/so chain.

DescribeFrequency: 9

State features in sequence or list observable properties — do not explain causes unless asked.

StateFrequency: 8

Match the expected response style for “State” questions.

CompleteFrequency: 6

Match the expected response style for “Complete” questions.

SuggestFrequency: 5

Apply knowledge to an unfamiliar context; concise, practical points score best.
