I have been teaching Physics for 35 years and have been an examiner for Edexcel for over 20 years at AS/A level and IGCSE level. I initially decided to write some IGCSE revision notes for my niece to help her with her revision. and then I just continued with A level and regular updates. The notes have taken me 20-30 hours for each set, and will be an invaluable revision aid for students aiming for grades A* - E.
