FCRIT student and I teach maths and chemistry at primary school and secondary school level in Mumbai with smooth communication skills in English as well as Hindi.

I have seen all the qualities of a great and wise teacher in Gaurav sir, he is a fluent speaker as well as good interpretor that means if a student who doesn't understand English properly they have nothing to worry about because he can interpret scientific and technical terms in hindi properly.
I recommend highly for other students out there to join classes and start learning from Gaurav Sir.
