            The Corona-crisis has led to many announcements of changes to courses.
            We are interested to find out which courses still need to improve to achieve the excellence we are accustomed to so we can follow-up on the issues that still persist.
            
            We know of the following announcements: https://wiki.fsinf.at/wiki/Course_reactions_to_coronavirus/(W)Inf
            If a course is missing, or outdated, please update the page, it helps us represent you!
