Key examiner messages
Top priorities from the principal examiner before you revise
A significant portion of marks was distributed across Mechanics (Forces & Momentum), Standing Waves, and Thermal Physics.
In Paper 2, candidates who could comfortably relate graphical gradients to physical constants scored highly on kinematics and thermal rate questions.
Conversely, many students lost marks on qualitative descriptions—such as detailing the process of reaching terminal velocity, or explaining the consequences of introducing a parallel resistor in a circuit.
In Paper 3 (Option D: Astrophysics), standard calculations involving the Hertzsprung-Russell diagram and luminosity-mass relationships was a reliable source of marks, whereas qualitative explanations of Cepheid variables and cosmological redshifts proved more challenging.

Command word playbook
How to match each command word to the expected response style
Match the expected response style for “Determine” questions.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Show” questions.
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Match the expected response style for “Outline” questions.
Match the expected response style for “State” questions.
