These parents really dumped their kids in some hell hole of a state school just on the vague off chance that they might get a place an an elite university? Really? Although if they sent their kids to a prep and then they failed to make the grade, I suppose the parents could claim they had an ulterior motive so nobody actually knew the truth.
As for the DC who've been rejected by Durham, Oxbridge, St Andrew's & co. They're going to get drunk, cook pot noodles, play their favourite sport, miss a few deadlines, make new friends in their first term, spend the next term trying to get rid of those same friends, fall in love, fall out of love, sleep with some unsuitable candidates, try vegan, try different pronouns, play musical instruments, try things they shouldn't, stick a traffic cone on top of a British Empire statue, protest, be protested about, pour bubble bath in a fountain and have a student experience just like thousands of others who have also been rejected by one or two (perceived to be) elite universities. Best of all, they won't be stuck in their home counties bedrooms, because they're growing up and having fun. Maybe it's time to cut the crap about redirection and taking another path to greatness. Just a suggestion.
