 My name is Sonar. I am from JSPM Rajarishi Shav College of Engineering. First of all, I will congratulate the NPTEL team who has conducted the online certificate courses. I am taking the manufacturing system and technology. In these courses, various points are matched for my regular university syllabus. It is very helpful for my regular studies. This online certificate course is very helpful for me and my friends. I am also interested in other online certificate courses. It is very useful. I will give you one suggestion for NPTEL team. Please create more awareness for NPTEL online certificate courses. It is very helpful for you and me. Thank you.
