this teacher is so irresponsible. he's forever late for lesson or better still doesn't even turn up and another teacher has to take over. his phone will ring in the middle of lesson. often we won't be able to understand what the hell is he talking about. he just cant explain properly and he will start speaking mandrin. he even told us that sometimes he doesn't know the ans for the exam qns and he just has to pick the best ans from the student to be the correct ans. he gets such high salary to walk ard pretending to solve IT probs. he doesn't deserve that pay. quit it.. stop living in the thought that you're such a awesome supreme figure.
