I have been teaching high school science to top-level students in private international schools for the past 13 years, and I have taught a wide variety of curriculum including IGCSE, A-Level, Advanced Placement (AP), and the International Baccalaureate Diploma Program (IBDP). I have Qualified Teacher Status in the UK and I am a state certified teacher for grades 6-12 in chemistry from the University of Florida in the USA. I have a TEFL certification, and have been successfully teaching and tutoring ESL students for more than 13 years. My chemistry students have been accepted to top universities around the world, including Oxford and Cambridge.
