In the news it has suggested the restricted measures / social distancing etc may be in place for up to a year. Of course we don’t know whether this will actually pan out and if it does whether the schools will be closed for a large proportion of this. However, I think it may be possible that all kids that are currently at school whether primary or secondary (except for those supposed to be doing exams this year) may be literally repeating a year so they all leave a year later.
In the grand scheme of things, if the situation does turn out to be fairly long term, this may be a solution.......
