I think in the UK they will go with predicted grades and offer university etc places based on that.
I worry about the LC exams - I know they wanted them to go ahead so that the students would be ready to start college in October, but I have seen a suggestion that in order to keep numbers lower (and social distancing easier), 1st year undergrads might not start until January.
NI schools finish up end June, don't they? Hardly worth taking them back for 3 or 4 weeks, I wouldn't have thought. Scotland have said no school til September.
