Key examiner messages
Top priorities from the principal examiner before you revise
The 2023 Pearson Edexcel GCE Physics (9PH0) papers maintained a high-tier challenge level (overall 3.8 out of 5 difficulty rating).
While Paper 1 and Paper 2 balanced standard conceptual questions with rigorous multi-step calculation tasks, Paper 3 (General and Practical Principles) served as a major discriminator.
It heavily tested experimental uncertainties, logarithmic data analysis, and non-trivial mechanical setups, pushing candidates to apply their physical intuition to novel scenarios.

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.
Match the expected response style for “Determine” questions.
Match the expected response style for “State” questions.
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 “Show” questions.

Examiner notes & key calculations
- Bald Answers: In "show that" questions, candidates often wrote down the final value without showing intermediate substitution steps, automatically forfeiting the marks.
- Vector Sign Errors: In mechanics questions, particularly projectile trajectory calculations, many students failed to assign opposite signs to initial vertical velocity and gravitational acceleration.
- Spreadsheet and Coordination Literacy: Candidates struggled to translate physical relationships into spreadsheet cell equations (e.g., G11 = F11/B11) or to read logarithmic scales with changing grid-line divisions.
