Thank me. Kelmond

jingying ar...
what nvm?
faster post the hw so we can do during the weekends.
dont be so lazy already. ._.
cannot work, just copy and paste the questions for us or printscreen.
i think you better post it earlier or else later all of them come after you.
HAHA! :D

shit.
i have some prob with uploading the qs.
i'll upload by friday!
sry for inconvenience caused!
SRY!
but anw, chem nxt wk mah!
so nvm la hor!
SRY!
