In swami vivekanand model school the teacher of chemistry for class 11th and 12th Mr Santosh tada never came to class in whole year. He don't even have the basic knowledge of his subject and when the session is about to end he appoint a private teacher on his behalf to teach for just a few weeks.
He is spoiling future of many students. Please take an immediate action against him.
Hope for a quick action from you.
