 Hello, everyone. I am Arun Kumar working as a senior grade assistant professor in Ramquan Institute of Technology, Rajapalayam, Tamil Nadu. And indeed I am very happy to share the feedback and the impact that NPTEL had created in my career. So far in NPTEL, I have completed 17 online courses and I have earned a two domain scholar certification, one in patent and IPR and other one is on faculty domain and apart from that I have earned a motivated learning certificate. So, being a teacher it is always important to be get updated and in that way the courses which I have done through NPTEL platform have enabled me to get me updated in the field in which I am having interest. And in fact in addition to that the courses that I have learned under the domain patents and IPR had helped my career. So once again thanks to NPTEL.
