Argh!!! I juz realised that teaching my bro is sooo difficult!!! His exams r lyk nxt wk n i have kindly taken up the arduous task of coaching my bro. I nearly pulled out my hair n vomit blood in frustration while teaching him!! He is lyk SOOOO stubborn n refuse to admit that he is wrong!! Grrr... Cant believe i actuali accepted the task of coaching him. Shuld've juz asked my dad to hire a tutor for him but ohwell.. haiz.. I juz hope i dun die of severe loss of blood after his exams is over!!! =X
