Trust me sir, most of these south asia teachers, they dont even speak in their native tongue or English, but rather something that i call a hideous combination.
But, ususally, the schools that have cambridge AS and A2 are generally good, then again in the context of South asia, sir, I want to request something of you, for once in your lifetime, take a tour of south asia schools, the ones that normal people go to, not the extremely rich, and you will see that ever1 goes for tuition.
I study by myself, and because of that the teachers hate me.
