Denied to sit for an exam

I am writing this review with a bleeding heartv and also frustrated. I have registered my lil brother for engineering studies and this is a time for exams and there is a policy in place which exclude them from sitting for an exam because they have not reached 40%year mark this is wrong. We have paid for these services which our children are denied to access. They are bul**** left and right and this even haults or prevents them from progress and there is no mechanism in place to support and take students' grievances
