They have lecture materials(ppt) you can download on NPTEL... Give up on complaining on youtube, instead post it on their feedback forums of NPTELthrough Swayam
@@dushyantsaha759 well buddy FYI I know this shi* is there on Swayam portal and I have given the feedback over there too, and I ain't complaining. I just shared my opinion that how bad this whole video is. And ofc the video is on YT so I have full rights to express disappointment if the content isn't good.
