A math Physics paper 3

A math paper 1 was simple, everyone was laughing their way out of the examination hall but not me. I admit that the whole paper was "chicken", but I have got a lot of simple and straight forward questions, but I do not know how to answer them, not that I never study, just that all I have study very hard did not came out, and those I dunno keep coming out like water from a running tap. Example, I study trigo the whole morning but only 1 question of it came out that only worth 3 marks. Good luck to myself, Sorry Ms Lim, I have disappoint you, hope all I have learn come out in paper 2.
Next, was physics paper 3, all of us had a hell difficult time doing and following the instruction, lucky I manage to do and try my best. Maybe I could get score quite well here.
