SIGH... tink i kind of screwed my math paper 1 todayy. It was all fine until the last question where i had to choose between two questions, one on first order differential equations, and the other one vectors. unfortunately i'm hopeless in both topics, but i had to choose between one of them, so i chose first order DE. it was all fine until the last part, where the moment i see the question, i knew it's beyond me. so after attempting for a few minutes, i gave up. and i thought, maybe i should try the vectors question. and i stupidly did. So i started doing vectors, and i realized i'm not so confident about vectors after all. so after trying like half the question, i thought,maybe i shouldn't be so indecisive. so i went back to do my first order DE. but it was too late. i've already wasted like 15 min. oh shit... and with 15 min left, i was still stuck at the last part. so i gave up, and went back to a previous question which i left blank (also cuz i knew it's beyond me the moment i looked at the question).

ahhh. i guess it's alright if i can't do a question, cuz if i really can't do, it can't be helped. but unfortunately, at the last few min of the exam, i went to check my first question. AND i found out a stupid mistake i made! ahhh. i cancelled the whole thing and started writing the new working. but before i could find anything, time was up!! oh my god. that really made me panic and i suddenly felt that i have no confidence in my other answers, cuz i could have possibly made such a stupid mistake for other questions. die die.

oh well. all is over, and what i can do now is to work harder for paper two and make up for my loss in paper 1, HOPEFULLY. tomorrow is chem paper. and i'm quite sure i'm going to die for it, after trying the last year rj prelim paper which was totally -cannot make it-.

i was all worked up again just now when i started revising for chem. i put my notes in front of me, and started to link up wat i learnt. but my mind was totally blank. i tink that's what people call blacking out. i sat there for half an hour, trying to figure out what my notes is talking about. omg i'm glad i blacked out just now, and not tomorrow at the same time, where i'll be sitting in the hall for my chem paper. and knowing the standard for rj chem, i can't afford to lose ANY time. so there, good luCK to me~
