i do not agree with this statement that students should paid for good grades.yes rewards and grades are good but financial rewards are not important.Because by get paid on the basis of good grades may harmful for student’s characteristics it may demolish his personality and he/she may became more greedy.pay cash reward may tend to him towards earning rather then learning.
some people think that cash paying on the basis of grades should be helpful for student to meet his/her expenses but it is my notion that rewards should be in form of certificates,books,pen and most important scholarships.Because different researches told us that scholarship proven more helpful for creation of healthy competition between students.so finally students should not be paid on the basis of grades.
