Exam....time mistake

Lol! First time unable to finish the paper! SAD! Teacher can u plz remind us when the exam is almost over and plz write the time properly. I read the time wrongly, it ended at 9.30 but i read the 3 as 5 i thot there was another 20minutes for me!! This time de result sure... haiz. On the other hand, i will never expose my answer to anyone else in the next time. That day i put my answer sheet near the edge for some 'purpose', the teacher came to me and asked me to cover my answer. Hopefully, she wont write my name on the piece of paper. XD
