Chemistry:Chem teacher teach until very 乱七八糟. Is nothing la, but then i dunno how is like, i dunno how we go in class, coz after bio spa, then we doing bio W/S, then she say put away our things. ok la its ok to say but i dun like her attitdue. I fgrgot what she say alr but then very "why we dont understand what she say la" . Then split us into groups, then must answer question, then the group with the most points can get extra time for quiz. Where can like that one lor. Then is like i ask her question hor, coz i really dunno what she talking alr, then she nvr even explain properly la.
