Some pple are just plain lazy and attribute the failure of their
exams to poor memory.
hmm. it's probably true.
i used to do really badly in poly, i believe it's because i
didn't really cultivate a good study habit. i didn't know how to
study, and i defintitely can't swallow books and somehow i just
didn't get the lessons and stuff. and every semester i failed
something.
but now i found my study pattern. stuff like..
i cannot study at home, i can only study in a really really
quiet environment like i'm alone, or in public places like
coffeebean where there's abit of background noise and
distraction.
i need to make my own notes by copying. the writing helps me
remember. even if i already have the lecture notes, i remember
better by copying notes.
and i just got my result, 82/100 = distinction!
