Don't worry Boba. I still have red spot TYS 2 years ago. I think quite pointless to memorise if you don't undertsand concepts. "Go uni sure suffer even if u memorise and got straights As for A levels. " Is this true? This is quoted from many of my teachers. Hee. Lucky I don't memorise. But this definitely put me at a disadvantaged postion since I have to derive the formulas again during exam.
