There're a lot of grammatical errors in the teachers spoken english. i suggest they should improve their english so that the students will not study those mistakes

u have no right to speak about teachers like that because they are the ones who guide u to ur destiny, i understand that they need to improve their english but we are not the ones to judge them. So pls leave the habbit of judging others!!!!!

its not good of u to do so. without teacher's videos it wud be more difficult to learn.if u know too much,keep it to yourself.sorry if it seems wrong

u r a kind of mucture person, pointing d 1ns who make u better
