Hi My name is Gary and I am a retired chemistry teacher with 30+ years experience of teaching chemistry to A-Level standard. I have taught in various schools in the UK and in international schools in Spain, Egypt, Bahrain and China. I offer a personalised tutoring service for students living in and around Valencia and also worldwide via the internet. Whilst my specialism is chemistry I can also help students with physics and mathematics up to iGCSE level. If you need help with your studies just send a message via this website and I´ll do everything I can to help you improve your grades.
