In English
You should not be upset by that; work hard, try again, and do well the next time. Marks may seem important but not earning bad remarks is even more important! Make sure your behaviour does not attract unfavourable comments from others. Be careful that you do not earn a bad name. Let good and noble feelings be the basis of your conduct. Wherever you go, people must say, based on your good conduct, "This person seems to be a student of the Institute of Higher Learning." is not interested in earning a reputation; all that wants is that you must earn a good name.
