Here is a problem from the 2022 ENGAA/ NSAA Cambridge Admission test. I gave myself a problem to solve to try and highlight problem solving techniques and how to learn physics.
Please note that is applicable directly to A Level Physics (all exam boards - AQA A Level Physics, OCR A Level Physics, Edexcel, CIE Cambridge International 9702, etc) and similar courses such as IB Physics, AP Physics, etc.
The question is about a pendulum and it involves a mixture of conservation of energy and conservation of momentum. I greatly enjoyed it!
Please note that this is not an official solution, I am not affiliated with Cambridge, and please check out the official paper here, I did Q11 from section 2 2022 (sorry there is a typo I wrote 2021 in the video): undergraduate.study.cam.ac.uk/sites/www.undergraduate.study.cam.ac.uk/files/publications/engaa_2022.pdf

This problem can be used as a revision tool on how to learn physics for Paper 1, Paper 2, Paper 3 and admission tests. Hope it is useful!
