Exams are very important for us to show our abilities to understand the lessons and to know the clever students from the lazies and give them their marks with out cheating from teachers .. it happened by the way by some teachers ( giving students marks or steal marks from them ) although if the student doesn't deserve that ..
but sometimes I think exams are wasting for time specially when they depend on memorizing .. and we should only have monthly exams at least which means there is no mid term exams or final ..
Teachers also have 2 be merciful because we are suffering from the stress at school
