Bad school. Review on New Horizon Gurukul, Bangalore

Hii, My children are studying in this school in class 4 and I m really upset with the quality of notes being provide for English subject in this school. When we approached to the subject teacher that the answer given is grammatically wrong the teacher said that the convenor for English is Mrs Bhavna Chauhan and she has approved and we cant change it. This is the quality of education being given to the children and we really are worried about their future. I have even spoken to some of the parents for class 3 and their opinion is also the same. Our only question to the management is after paying such big amount why our children are not getting quality education. This really upsets us. I request to the management to please take strict action against this teacher as our children's future will be on stake if they learn such English. As it is a language we really want some action to be taken on this ASAP.
