I agree that cheating is not fair. But the fact is that if you always study hard , you might not get the results you expect. Some people study hard without consulting guide books, taking tutions and coaching classes.Those people are rarely sucessful.But some people do just the opposite.They study only the important and selected questions and consults guide books, takes tutions and coaching classes. In this way they reach their goal and get what they expected or sometimes more than that.Other people will not see how they achieved their goal but only their result.
