Students should speak up when they see someone cheating in class. Doing so lets cheaters know that people are watching and consequences will follow.

Indeed, students should notify their teachers whenever they see one of their classmates cheating on an exam. In this way, students would know that at any time they could be betrayed, which would reduce the risk of cheating and thus raise the level of students, who would be forced to study to pass.

But in addition, this attitude would be very positive on a social level, since it would promote non-tolerance in the face of corruption and respect for norms, thus creating rules of conduct that would remain in individuals during their adult life in society. In this way, habits of honesty would be generated that would benefit society in the future.
