Exam season is back and, with it, renewed emphasis on catching cheats. The involvement of teachers, police officers, parents, peers, students and others reflects a corruption of social standards. It is sad that each year must see an escalation of measures to deter those trying to cheat. As long as educational options for those who fail to secure limited places in higher institutions remain limited, there will be an incentive to cheat.
There is no telling how many of the candidates who sit examinations in any given year manage to get away with cheating.
