     Parents,teachers,even friends can put a lot of pressure on students to get good grades.Some parents threaten to punish for bad grades or offer rewards for good marks.That makes most students think of cheating at some time.But these kids also know that succeeding on a test by cheating is not really succeeding at all.

     When students cheat,they are less likely to really understand their schoolwork.And when you don't understand your schoolwork,your grades will probably suffer;cheating can only get you so far.The bottom line is:If you don't learn it now,you'll probably have to learn it later!An honest C will get you much further than a not-so-honest A. Face it:Cheaters never succeed----and pay a high price when caught.

     So,that's why you ought not to cheat.Be honest and open about who you really are.And you'll one day find it so meaningful to your personal life.
