Incidentally my sons were among those rejected by Durham (though one was accepted by Oxford) and they both got an explanatory sentence on Track saying the reason was weaker personal statement.
Their PSs were exclusively subject related, and seen as strong by their school. DH and I have both read a good few PSs and were also confident that theirs were good.
So we were left concluding that either:
a) the extracurricular stuff did matter for Durham - I've since seen on their website that they claim it does - and it disadvantaged my sons not to put it down
or b) Durham just has a few standard rejection sentences, and they chose that one because they couldn't realistically say it was down to academic achievement as our sons have all but one grade 9 at GCSE (and A* predictions).
This was for Humanities courses, not anything vocational.
So we were left a bit confused. The boys' school and DH's school advise those applying to Oxbridge and other 'top' universities to omit extracurricular activities and to focus on academic stuff, but we wonder if our two should have stuck in a sentence or two, just for Durham?
I do wish, whatever the case, that universities were clear and in agreement about this, and communicated that to schools. Tbf Oxford, Cambridge, LSE etc. do (subject only) and that message has got through. But tricky if a few others (well, Durham - didn't count against my sons elsewhere) mark you down for that.
