 Hey, I am Arunagiri and I am from Savita Engineering College and I took introduction to air paint performance in NPTEL. It was actually a very good course and most probably because I like aeroplanes and I had much more interest on taking about it. So the most, if you don't mind is that the teaching was very good of A.K. Gosar because I like this very much. And then it was mostly like, it was also practical based so that feedback is very good. Then any improvements to be made is like, you don't need any improvements because it is very good. That's all it is. Where do you plan to use the certificate that you get? I'll just keep it myself. Okay, great. I mean, I have a plan to do M.Tech in... Okay. I'll just pass in the gate and do an M.Tech in Kanpur itself. So that is really nice. Thank you.
