Is a sad news, the teachers are not to be blame because they have done their own part in the classroom, so is left for the students to still study hard on their own whether at home, burding or wherever they found their selves. Again, the parents are to be blame some how, because some parents allow their children to go out any time they like and come back any time they like too. Anyway, exam na luck, at times whether u study hard or not if u wan pass u go pass.
