Tutor and teacher of Science and Maths to GCSE/IGCSE level; and Physics and Maths to IB/A-level. I have taught in Japan, St Helena, the UK and Germany, and I have been head of Maths and Physics at various times. I started by teaching undergraduate Physics students while doing a PhD at Cambridge University. I also work as a freelance writer, and have carried out commissions for OUP's Kerboodle, HarperCollins, Kognity, and Cambridge Assessment. Apologies if you are looking for sets of past exam questions by topic amongst my resources. Back when I uploaded those, there was no explicit ban on doing so. However, TES have now informed me that sharing exam questions is a breach of copyright and I've had to remove them.
