Key examiner messages
Top priorities from the principal examiner before you revise
The May/June 2025 series represents a highly balanced yet rigorous assessment of candidates' grasp of fundamental physics principles, mathematical applications, and experimental synthesis.
Paper 41 (Extended Theory) anchors this suite with a diverse range of questions spanning all five core curriculum areas, including the newly emphasized Space Physics chapter.
While mathematical operations were generally well-executed, qualitative explanations and precise scientific terminology remain the primary differentiators between the top grades.

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.
Apply knowledge to an unfamiliar context; concise, practical points score best.
Match the expected response style for “Define” questions.
Match the expected response style for “Draw” questions.
