Yeah, I think the big issue with holding the exams anyway is that far more students would have failed, because they hadn't been adequately prepared for their exams. Students have been treated extremely unfairly, but that's only the first problem. The second problem is that they've had much less education than previous cohorts and this is going to have a continuing impact upon their academic careers and future employment if nothing is done about it (as seems probable.)
The problem is likely to be even worse for next year's cohort.
Although the exam cohorts have in some ways been the most unlucky, in another sense they are the most fortunate, as by the time schools shut they had pretty much completed their syllabuses and would have been moving into revision, so they have actually missed the least learning.
