Is it acceptable to create YouTube videos about exercises of a University level course ?
I struggle to follow a quantum mechanics course I need to take and thought about making YouTube videos where I explain the exercises and their solutions provided to us step by step. I already did that for two math courses last year, and not only did it help me a lot, it also helped other people that watched my videos. But some people told me to be cautious, because after all I did not create those exercises by myself and thus I have no right to talk about them in a YouTube video.
What should one do in those cases ?
