The decision to cancel seemed to be somewhat spur of the moment and due to much shouting about school safety, which in the face of circa 70% keyworker attendance seems to have failed, yet Y11s and Y13s have paid the price by losing their chance at sitting for exams they have spent months working towards. The decision is only 6 days old. In administrative terms, it is still feasible to salvage this and reverse the decision.
Just carry on for heavens sake with the reduced grade boundaries, papers that exam boards have already created for the 2021 season etc.
