Key examiner messages
Top priorities from the principal examiner before you revise
The distribution of marks across the papers was heavily anchored in Deformation of Solids and Oscillations, largely due to the substantial weighting of these topics in the practical paper.
In Paper 21, the mechanics questions (moments, conservation of energy, and dynamics) commanded the highest concentration of structured marks.
circuits and superposition also played a critical role, requiring precise application of Kirchhoff's laws and wave interference formulas respectively.

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