Bluestocking...my son went up to a top University last September. Not Oxbridge. He is just about the only non-public school, non-Southern, person on his course. I earn a great deal less than £25K!
He did get a small non-repayable grant due to us being poor! However, he has not got so much money he doesn't know what to do with it! There were bursaries for which he competed,but sadly did not get.
He would not entertain applying for Oxbridge as his perception was of a place full of public school 'toffs', and yet he has ended up at exactly such a place! I think it's probably due to the subject he is studying, which is academic and vocational.
Luckily he is very tight with his cash, and has saved a fair bit over the years of birthday money, part-time jobs etc, and so has a cushion. He is not working now as he finds the course so time consuming that it's not possible for him. And of course the others on his course have very well off parents to support them.
His school have been very supportive over the years, especially so in the early years when he was disruptive and difficult.
I have also expended a lot of energy and stress to get him where his is now. So yes, I did 'push' him. But only to fulfil his own potential, not my expectations. His sister is at a local college doing a business foundation degree while working. It is essential to encourage your child within their own abilities and temperaments.
And being from a poor family should not dissuade DCs from going to University if that is what they want, and suits them.
