Ei....... damn tired now, but i still need to study now.. cant sleep at all..
Today is my last day mid term of ECON, i don't know what question would come out on exam paper. I try my best to study, but i feel scare that i would getting a bad result. Cost management and QBM i uses around four days to study those subject, but when i on the exam hall, i cant do well.. I don't know what teacher need me to do, may be i really cant understand the question, but the theory and basic question i still can done well.. What i less?? Izzit my languages problem?

I damn regret that i never learn better at English languages before.. I damn hate myself, why so like to play and never try to study earnest at secondary school..
i know that now i need to improve more in m English, if no my future just a darkness road.
