While 1.5-hour lessons offer better time for money ratio, this option tends to be more suitable for older students (IGCSE and A-level or equivalent). Younger learners generally have shorter attention span resulting in 1-hour lessons being more productive for them.
I travel to Lamai, Chaweng, Bangrak and Maenam areas of Samui for no additional charge.
I hold a postgraduate teaching qualification from the University of Nottingham, U.K. and a BSc (Hons) in Physics from the National Research Nuclear University MEPHI as well as a decade of teaching and tutoring experience.
