 Hi, I am Balaji and I am from Vellamal Institute of Technology and I am studying BEE Tripoli second year. I came to know about the course in my college. Some of the professors suggested me to log in through my mail and check out the NPTEL course. First of all, I was feeling that much confident about this but later on when I watched those videos I was really impressed by those professors, their teachings. Which course did you do? Introduction to Programming in C and I got weekly assignments and I wrote those assignments with the film work. Initially I couldn't get all those, pass all those assignments and get film marks but later on by getting help from others and asking doubts in those question sessions I came to, I wrote from that problem and after attending a few months I got confident of writing those exams. Then I registered, it was quite good. This exam is online registration exams. It had four questions and you need to pass eight test cases to get those questions correct. Then I wrote three questions of the four questions. And where do you think the certificate will be useful to you? It will be useful for my placement and I want to join an IT company every month for this so as it is organized by IIT's and NPTEL's government. Thank you.
