 In some cases, usually in high schools, fail marks may be compensated with high passes, provided the average mark is a pass.For example, a mark 4 and 9 would average at ((4+9)/2=) 6.5 which makes for a pass.Compensation of marks is not always allowed in the course specifications, or a lower limit may be set (e.g., a mark below 4 may not be compensatable).
