Not going back to Edinburgh this year. Continuing University online.

Hi so I'm a first year engineering student, gonna be 2nd year this September and I'm and international student who is at home now. I don't have a plan to go back to Edinburgh anytime soon (probably until next year) mainly because my parents are a little bit worried of me going back there amid all this covid outbreak. I understand the uni is going to run a hybrid system - which I honestly still don't get if its completely OK that I don't go to the university at all. Will continuing online hugely affect my studies? Any of you international students not planning to go back anytime soon as well?
