Key examiner messages
Top priorities from the principal examiner before you revise
The May 2023 IB Physics Standard Level (SL) examination is rated at a 3.4 out of 5 in difficulty, representing a solid but fair challenge.
While standard calculation-based questions were accessible, the papers stood out due to their demanding qualitative justifications and the intricate integration of multiple topics within single questions.
For instance, Paper 2 combined circular motion, gravitational energy, and conservation of momentum into a single 14-mark sequence.

Command word playbook
How to match each command word to the expected response style
Match the expected response style for “that” questions.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Determine” questions.
Match the expected response style for “State” questions.
Apply knowledge to an unfamiliar context; concise, practical points score best.
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.
