Key examiner messages
Top priorities from the principal examiner before you revise
The 2024 exam papers presented a standard to high difficulty level (3.5/5.0), in line with recent historical trends.
While the multiple-choice questions (MCQs) across Papers 1 and 2 served as accessible entry points, the unstructured descriptive questions and multi-step synoptic calculations required high cognitive effort.
Specifically, the latter halves of Papers 1 and 2, along with the extensive data analysis tasks in Paper 3, tested candidates' ability to chain multiple conceptual frameworks together under strict time constraints.

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.
State features in sequence or list observable properties — do not explain causes unless asked.
Match the expected response style for “State” questions.
Match the expected response style for “Deduce” questions.

Examiner notes & key calculations
- Unit Conversions: A persistent source of dropped marks was failing to convert temperatures from Celsius to Kelvin in ideal gas equations (pV=NkTpV = NkTpV=NkT) and kinetic theory calculations (12m⟨c2⟩=32kT\frac{1}{2}m\langle c^2 \rangle = \frac{3}{2}kT21m⟨c2⟩=23kT).
- Uncertainty Arithmetic: Many candidates struggled to properly double the percentage uncertainty of the diameter when computing the total uncertainty for a coin's cross-sectional area or volume.
- Moment Definitions: In Paper 1, omitting the term "perpendicular" when defining the moment of a force about a point was a common error that cost easy marks.
- Intermediate Rounding: Candidates who rounded values prematurely in multi-step equations (e.g., in the subsea power transmission cable problem) failed to achieve the exact "show that" values.
