Key examiner messages
Top priorities from the principal examiner before you revise
The Summer 2023 Pearson Edexcel GCSE Physics Foundation Tier papers presented a well-balanced and highly accessible assessment of the specification.
While designed to accommodate standard foundation-level skills with ample recall and single-step calculation questions, the exams cleverly integrated some higher-order cognitive demands towards the end of each paper.
This tier successfully tested student stamina and precision across all key chapters, culminating in an overall difficulty rating of 2.3 out of 5.

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