Chemistry

The chemistry exercise given by "suet+yin" drives me crazy instantaneously! Had he gone mad? What I mean was he can't even figure himself out on what he is teaching and yet he's giving us exercise that I don't think he has ever covered during his day lesson. And I am impressed by one(maybe a few) of his quote

"I think what I've teach is more than enough for all of you to score well in the exam, if you don't I really dunno why"

"If you keep on going like this, the year end exam I'll have very little thing to mark"

WTF?! DO he have a clue on what he is saying? he is trying to put all of the L6M's future in fire and burn it all up?

Please la school admin, change the teacher.
