 I am from IIT Madras studying in Electrical Engineering. I took a course on wireless, which is principles of OFDM, CDMA, MIMO systems. Because a good course it covered the subject really well. But only thing is the type of questions, the difficulty of the questions could be slightly increased and the examination was also very well organized. And I look forward to having more such courses. Thank you. We are from IIT Raj College in Chennai. I am Manastha. I am studying. In the NPTEL courses both of us have chosen the infrastructure economics. The course was kind of good. It was really good. The way they have given us all the NPTELs and the video presentation we was clear about what he was explaining the professor. Our professor was an alum in NPTEL. And how did you know about NPTEL? Actually one of our seniors had recommended this to us. So we liked the way it was being done, teaching online and then giving us the tips. We had a few assignments in between so it was very helpful for us to prepare for this. How was the portal? Was it easy to handle? The online courses were NPTEL. We didn't have the online course. Oh, you were talking about the video and all. No, where is the website where you all were going and seeing the assignments. Was it easy to use? Yeah, it was very easy to use. There was no problem with the registration also. Discussion for announcements. Whatever questions we were asking we were getting back with clients. How was the exam today? The exam was good but we get the good results. And where do you think you will use this certificate? Will your father recognize this? Yes, and plus we are both economics students we are doing business economics so since we have taken up infrastructure economics it will give us more idea about what is going on and we have just specified with what we are doing.
