Thank you both.
Do you know whether this is affected by moving to a different school to start year 12 (in the year where they should be going into year 13)?
DD is ('correctly') in year 13, having moved from one grammar school to another at year 12. Amongst her general group of friends is a girl from the year above who repeated year 12 at DD's previous grammar, someone in her (DD's) year who did year 12 elsewhere but then returned to start again, someone who got a (new) place at the aforementioned comprehensive to start again and at DD's current school there is at least one ' restarter'. I have a friend whose DC restarted at another school then moved mid (second 12th) year to a different school.
TBH, I can't keep up

I think the St Olaves affair had a lot to do with it, at least at the beginning of the 2017/18 academic year - in fact, I know it did in one case.
