In my opinion, the answer should be no. While I believe that turning on cameras may result in a better learning environment, I don't think it should be a requirement, or go towards a grade. This situation forced us all into quarantine, and everyone was forced to do virtual learning. People may not have a good environment to work in, for example, if a student has fighting parents in the background. Others may simply be very introverted. I think as long as the student is completing all tasks and absorbing the information (even if he or she is not at the computer at all times), it should be fine.
Side characters only appear in a few episodes, have lives and stories of their own, be less developed than in short stories, and be present in every single scene.
