Kendriya Vidyalaya Sangathan — my nephew is in class 7th c of kvs vigyan vihar

It is a humble request that student (Granth class -7th c) is ignored by class teacher and his copy is not checked by teacher only by the student. This shows that teacher are not performing her duty and only student is guiding the students and also no diary is maintain by the students. Unnecessary instrument are taken by students in the class but teacher is not checking it.
