I would like to convey my heartfelt gratitude to couple of individuals who have guided me through this journey of MATHEMATICS classes taken by Sourav Sir were immensely helpful. I always made it a point to attend his lectures on sentence correction. Apart from him, guidance of other teachers helped me lot as well. I would say, it is the guidance of these individuals that shaped my journey to a great extent. I would safely suggest any aspirant to get in touch with these individuals.
