Nobody is expected to finish the paper in the allotted 2 hours. Like in the BPhO, you should consider spending your time on 2 or so long-answer problems.
Please read the context and especially background information carefully. Many problems involve using approximations and information in the context is important in justifying these approximations.
Show working! A final answer by itself will not give full marks. Refer to the long-answer mark scheme for more information.
The exam will cover content from high school level physics, with a focus on the topics covered from NCEA levels 1-3. Both juniors (Y9-11) and seniors (Y12-13) will sit the same paper, but will be awarded separately. The difficulty of the questions is similar to that of the British Physics Olympiad.
The paper is split into a multichoice section (30 marks) and a long answer section (80 marks). Students are encouraged to spend around 30 minutes on the multichoice section and 1.5 hours on the long answer section. Here is the question distribution by topic for the 2025 paper.
Multichoice section (30 marks)
7 Mechanics
4 Electromagnetism
3 Waves
2 Modern physics
2 Themodynamics
2 Miscellaneous
Long answer section (80 marks)
One 20-mark question on mechanics, waves, electromagnetism and modern physics respectively.

Math pre-requisites
Some questions in the paper may assume some basic calculus knowledge. Participants are expected to know how to:
Find derivatives and integrals of basic elementary functions
How to solve simple differential equations: only separable differential equations will be in the paper
How to write physics formulae in terms of variables and their derivatives
Anything beyond the above will be clarified in the question itself within a information box.
