I have been thinking to get associated with the course since a long time. This course, at present, is being offered by one of the senior teachers Prof. R. C. Sharma in our Department. One of the special characteristics of the Department that makes this institution unique is that we, the faculty, very happily share, actively participate and even audit the courses of one others. This is something I have not come across at any other institution. I feel great to be the part of such a great institution of learning. Hope some day I take up this course on my own for at least one academic year. I feel indebted to some of the senior faculty in the Department who have agreed to share courses with me, in particular, to Prof. R.C.Sharma, Prof. R. Gargesh,Prof. Tista Bagchi, Dr. S. Satyanath, Prof. R.K. Agnihotri and Prof. K.V. Subbarao.
