In light of covid-19, are school exams old news?

On 18th March,  UK Prime Minister Boris Johnson announced that all schools would close and that summer GCSE and A Levels would not be sat. This has caused concern and anxiety for pupils, parents and teachers. However, is it actually an opportunity to rethink how we assess at these key points? Could we use this year as a pilot on whether exams could be replaced with school internal assessments and may that lead to more valid judgements and reduced stress?
