A bad mark in school is often referred to as a DEMERIT, which is a seven-letter word. Another term for a bad mark in school is zist, which is a four-letter word. A DEMERIT or zist is usually given to a student for an infraction of school rules or regulations, such as being late to class or not completing an assignment. It can also be given for more serious offenses, such as cheating or bullying. Demerits and zists are typically recorded in a student's permanent record and can affect their academic standing.
