It is bad manners in the classroom to look for what our neighbor had written, or try to see what mark he has received without being permitted. It is good manners for them to help each other if we have the same desire and the teacher allows to it. In examinations and in certain kinds of written works, it is dishonest and foolishly to help or to ask help from others. When one student does so, much larger values are destroying. One may not agree to examination system, but at present it is basically the only measure that the teacher and the rest of the world can depend to decide if or not each of us meets the requirement.
