my parents and overall family attitude was very much one of aspiration and opportunity and fully supported me in extra curricular a much as they could, helped me travel to a school so far away to get a good education etc etc. It's not the same as being disadvantaged by poverty in the way some other kids are
@LilMidge01 you've put it really well (much better than my attempts to explain). In universities, we're really trying to widen participation and get kids whose families had never thought of even going past GCSEs, let alone university.
And I am trying not to say that poverty = lack of interest in education.
I once taught a really bright undergrad - amazing intellect, and she went on to do a PhD (I'd advised her to think about this in her 1st year, I could see how good she was) - and I remember chatting to her at a conference when she'd got her PhD - her family story was of 'respectable' poverty and solid working-class values.
She then told me that in her family, she was the first to get A levels, let alone go to university.
That's the kind of widening participation we're trying to encourage.
The OP's issue is that her son won't necessarily interview well. There are many solutions suggested on this thread and IME, admissions staff, and university academic staff, will work to make 'reasonable accommodations/adjustments' - as we are required to do by law.
It is nothing to do with the OP's poverty. And it is disingenuous for the OP to suggest that it is. Her DS it at a reasonable comprehensive, not a "sink school" and in an area where the general culture will be one of aspiration, and assumption that A Levels, then university, are a reasonable & doable life plan.
For far too many children in this country, still (eg my lovely undergrad/PhD student), this is not the case. Even staying on at school to do A Levels is seen as something not possible or 'not for us.'
