Key examiner messages
Top priorities from the principal examiner before you revise
The May 2023 Physics Standard Level exam suite represents a solid challenge, sitting at a 3.5 out of 5 on the difficulty scale.
While Paper 1 contained several standard recall and single-step calculation questions, Paper 2 and Paper 3 introduced highly contextualized scenarios (such as the toy water-rocket and the cubic force ball rebound experiment) that required students to deeply apply conceptual frameworks rather than simply plugging numbers into equations.

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 “State” questions.
Match the expected response style for “Deduce” questions.
Match the expected response style for “Outline” questions.

Difficulty Verdict
The May 2023 Physics Standard Level exam suite represents a solid challenge, sitting at a 3.5 out of 5 on the difficulty scale. While Paper 1 contained several standard recall and single-step calculation questions, Paper 2 and Paper 3 introduced highly contextualized scenarios (such as the toy water-rocket and the cubic force ball rebound experiment) that required students to deeply apply conceptual frameworks rather than simply plugging numbers into equations.
Where the Marks Are
A significant portion of the marks in Paper 2 were concentrated in mechanics and wave phenomena. The toy rocket question (Question 1) alone accounted for 15 marks, testing kinematics, momentum, and rotational mechanics. Wave phenomena (Question 3) offered another 9 marks, rewarding clear explanations of double-slit interference. In Paper 3, Section A focused heavily on experimental uncertainties and thermodynamics, while Option D (Astrophysics) was dominated by Hertzsprung-Russell diagrams and cosmology calculations.
Examiner notes & key calculations
- Uncertainty Propagation: In Paper 3, Question 1(d), many students struggled to calculate the absolute uncertainty for Fmax3 F_{max}^3 Fmax3, forgetting that raising a variable to the power of 3 means the percentage uncertainty is multiplied by 3 (yielding 15% 15\% 15%).
- Gradient & Linearization: A common pitfall in experimental physics is failing to show that a proposed relationship F3=kΔp F^3 = k \Delta p F3=kΔp is supported by proving that a line of best fit is linear and passes through the origin.
- Rotational Kinematics vs. Dynamics: On the circular motion and rotational questions, students often failed to recognize that linear speed at the rim depends directly on the angular velocity v=ωr v = \omega r v=ωr.
