if u use average marks of students to determine passing grade, there will always be a number of failure student.
Unless everyone has the same mark.
i think its CRUEL and UNFAIR
i know its hard to get 100% pass but it doesn't mean you have to reserve failure 'seats' making failure likely compulsory every year.
"i can assure you at the end of this year there will be at least 2 or 3 of you who will not make it to next level"
so much of being positive
p/s don't you agree 50 is a reasonable passing mark and used widely?
