Key examiner messages
Top priorities from the principal examiner before you revise
A significant portion of marks resided in core mechanical derivations and experimental methods.
In Paper 1, the practical question on wire resistivity and the 11-mark mechanics sequence on the van's deceleration in gravel tested precision.
In Paper 2, Waves and the Particle Nature of Light led the marks, heavily featuring the photoelectric effect applied to lunar dust and scale-drawn lens magnification.

Command word playbook
How to match each command word to the expected response style
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Show formula, substitution, and unit; method marks need visible working.
State features in sequence or list observable properties — do not explain causes unless asked.
Match the expected response style for “Deduce” questions.
Match the expected response style for “Assess” questions.
Match the expected response style for “Criticise” questions.

Examiner notes & key calculations
- Bald Calculations: Providing a correct final numerical answer with no intermediate substitution of values in 'show that' steps resulted in zero marks. Always write down the substituted equation first.
- Resolution of Vectors: Confusing sin(θ)\sin(\theta)sin(θ) and cos(θ)\cos(\theta)cos(θ) when working parallel or perpendicular to inclined planes was a widespread error on the car down the slope and the lunar dust particle vector question.
- QWC Structure: On the asterisked questions (the flashing LED and the falling-ball viscosity experiment), candidates often listed facts without logical chronological linkages. To secure the full 6 marks, arguments must follow a causal sequence (e.g., temperature rise →\rightarrow→ viscosity decrease →\rightarrow→ higher terminal velocity for the same drag force).
Analysis is paraphrased for study purposes. Always verify against the official examiner report and mark scheme.
