How COVID19 has affeced university students studies ,their mental health and their perfomances

This is not a essay. The number of words is 150 words maximum. All you must do is explain how Covid-19 has affected the studies of university and their mental health and how working at home is not the atmosphere to work in at all and how that can affect on the ability of a students performance in their studies. There are no references required. It is just an description/explanation of the above. Thank you very much.
