everytime my head was overloaded with digits, i felt like throwing up.
i like math, i do. but i guess numbers are not my yin fern. hehe.
tomorrow will be the last paper.
and probably the last time i'll be stressing my head off in there.
uwaah. better get back to permutation and combination.
if not, the probability of me getting an F in math wud be 99.9%
