I was sweating. Ms Ip neared my table and put the exam paper in front of me. I closed my eyes and opened them a fraction of an inch. There, on top of the paper, was a 33. My heart sank. Then my teacher took away the paper and put another one in front of me. I took it and saw an 88 in the mark box. The first paper belonged to my neighbor, Sally.
