Well, it depends, in my opinion, online classes aren't the best idea to implement, but that's life, we should comply if we don't want to spread out COVID19 virus. From another point of view, it is ok, because we don't have to quit our houses, and we can do everything from our homes. Furthermore, you can easily cheat on different exams and home assignments. For example, I found some guys writing my essays for me, for a pretty small fee. I would do my essays by myself, but unfortunately, I work and I don't manage to keep all this stuff under control.
