Sir really changed my life and that made me learn many things from him. When ever i give up he was always there to support me at moment. Coming to subjects. Sir has a great and vast Wikipedia inside you and which is shining like a sun giving light to many creatures so . He used to answer questions in a very systematic way the main thing the sir does is he reads the psychology of the student and understand his capacity and work performance . The thing which makes you special and unique from others is the way you teach which cant be describe in words but i personally say sir has unique machine of data stored in his brain and unique life changer He is the only man i saw teaching 24 subjects perfectly with fully filled with knowledge and fun They way he makes difficult things easy is one of the important key to my sucess Thank you for being with me sir.
