Don't like that lah. TS alr very sad liao, you all still here
hao lian.
O Levels no need to worry so much lah. After mid year, the teachers
should be giving the students a lot of practice papers (other
schools' prelims, past year papers etc.) and also, if you hard
working, then do your TYS. Sure can make it one. I got a friend,
Chemistry from F9 to A2 leh. No need so scared lah.
