More and more students are cheating in exams. It is now considered to be a major problem at colleges and universities. In every exam, some students feel the temptation to sneak a look at their neighbors' tests, or at textbooks. Some students even take tests for other ones. According to a recent poll, 40% of students have admitted to cheating in exams at least once during their college life. There are indications that such dishonesty is on the increase. Colleges and universities across our country have decided to take steps against students cheating. For instance, students cheating are not given marks, or some of them are criticized publicly. But none of these measures work effectively. We ought to make all students realize that if they cheat on exams, they will be dishonest in their future work, and in the end they will be entirely dishonest men.
