I know one girl in my grade that cheats. She always wears her jacket during exams regardless of weather and always has her hands in her pockets. In addition, she will go to the toilet without fail in the exam. One girl went in as well during a Year 8 exam and saw her cheating. Other than that, I don't think anyone else cheats. For us, it's really easy though, as the toilet hallts have changerooms behind them that markers have no idea about, so it's really easy to hide something in one of the hidey holes there (there are plenty). Still, I don't see the point, as all you are doing is wasting exam time.
