& also, the Unis would go bust if they didn't have any first years next year!
I would argue for making it an option for kids who've really struggled/missed significantly more than their peers.
We do this in my overseas private school routinely.
Mind you, kids see it as a fate worse than death; the stigma of being seen to have failed the year, all their mates moving on...but that might be less painful if it was, I dunno, 20% of them rather than one or two 🤷🏻♀️.
But definitely wouldn't be practical for the whole cohort.
