 Hi, I am C.V.S. Prasanna. I did B.Tech in Mechanical Engineering in J.N.T.V.A. College of Engineering, Anantapur, in Khandar Pradesh. After that, I pursued my M.S.E. in Physics at IIT Bombay. I have used NPTEL course repository as my reference for most of my engineering courses. Besides that, I did few NPTEL online courses, namely Engineering Mechanics, Introductory and Advanced Fluid Mechanics, Mechanics of Solids, Introduction to Operations Research and Basic Electrical Subjects. I did all of them during my B.Tech. These online courses primarily helped me to gain better understanding and clarity over the subject, and that acted like a boost in the preparation for GATE, IIT Jam, and few other exams that I wrote after my B.Tech. NPTEL not just played a crucial role in my exams, but also gave me an opportunity to explore various subjects, figure out my academic interests, and even the courage of my students. Overall, I had a great learning experience with NPTEL, and I am very grateful to NPTEL for that.
