"Chanchal sir, brings about the concept to clarity and to the approach of the students. He often make a healthy smile rather then getting nervous over the questions being put up by students, and give the solution with more simple and clear examples. He had being dynamic and active in nature, and often prepare well enough before class rather than just rough approach to throw way out. I as a student, was being pleased to be taught under his guidance and supervision.Hope he may get more laurels in this field. "
