social contacts, mental health
University is important not only because of the lectures, but also the interaction among students and faculties. Now everything is held online, it makes social contacts very difficult if not impossible. And this led to serious depression and other mental disorder. What's more, it is not efficient at all to learn online. There are so many technical problems happening during lectures, and this is a disaster for discussion-based classes. Sincerely hope we can go back to universities as soon as possible.
