I have been teaching Physics and Mathematics for over five years now. I ran a tutorial in Goa where I tutored students between the age of five and eighteen. Earlier this year (2019) I got TEFL certification and now I teach English to students from six countries for two different online portals.
I volunteered in India, Nepal, Srilanka, Thailand and Cambodia and enjoy teaching a lot. I am looking forward to connecting with more students so the learning and teaching can continue.
