 Hello everyone. I am Sumit from Maharashtra. I am currently pursuing M.Tech in textile engineering from IIT Delhi. I have completed my B.Tech in textile technology from HGGS Nandheer. I had registered for many courses in NPTEL. One of the courses I have completed is yarn manufacturing, principles of carding and drawing. The design of this course was very helpful in gate preparation and also in campus placements. The assignments, quizzes helped me a lot in understanding the course in a better way. NPTEL provides us an opportunity to learn from one of the best faculties in India and also to earn a e-certificate from them. Their content is easily understandable and we can also clarify our doubts via chats. NPTEL has all the characteristics of an effective online courses. It has well-developed presentation, easy access to the course, students' participation, assessment and evaluation, etc. And it's all for free. I would like to thank all the people who are making NPTEL better and better each day. And also urge everyone to make use of this platform as much as possible. Thank you.
