For all those cheating or want to cheat, please do not cheat. You are merely destroying the efforts of all the other hard-working people. Even more important is the fact that cheating is Haram, it is mentioned in a Hadith;
'One who cheats is not amongst us'

Won't measures be taken against cheating? It's not that easy, is it?
