In this video we do a full revision of Edexcel and iEdexcel Electric and Nuclear and Particle Physics. The video follows the Edexcel A Level specification but the physics is completely applicable to all exam boards in A Level Physics.

Please note that all solutions are non-official and there may be mistakes or better approaches and for official mark schemes and advise please head over to Edexce's website: qualifications.pearson.com/en/qualifications/edexcel-a-levels/physics-2015.html

They have fantastic questions and resources!
