I already know...

I will fail today's paper. Suppose to do 5 questions but I only done 4. Not to mention I know what I am writing for 2 of them but the other 2? Haiz...spend so long revising in the end? The result will be worst than the previous one, I know for sure! Sianz...have the 'giving up' nian tou...how? But already step one foot in, if I give up now...it will be completely down the drain... :( how???
