Can anyone explain the reasoning behind these year groups going back first? The way I see it, the littlest ones have got the most time to make up what they've missed. Year 6 are done with primary and can start afresh in Year 7. Surely priority should be given to those sitting GCSEs and A Levels next year, to prevent a second group of children having their exams messed up. Plus secondary schools are much bigger, making social distancing easier, and the children are old enough to understand the rules.
If the goverment is adamant that Primary should go back first, wouldn't it make sense to send the older ones in first? The older the child, the better the social distancing.
