This is always brought up in threads like this and it is untrue!
I've said time and again on different threads (under different usernames), that both my children went/go to grammar schools 18 years apart (so the exam has altered drastically and I am considered poor.
Neither of my children were tutored - I was a single mum on benefits with DC1 and on tax credits with DC2. I couldn't afford it. I also have no idea at all how to do the tests, so I couldn't help them either.
We live in a 100% selective county, there are no comprehensive schools.
I live in a social housing home and the nearest secondary l, if they'd failed, is shit. So they've got the opportunity they wouldn't have had if there wasn't any grammars here.
Sure there are more affluent children there, but I don't put it down purely to money, it's also the love of education and desire to achieve, that is lacking from a lot of the parents at the secondaries.
DC2 went to a primary that went into special measures whilst she was there. The school still requires improvement, several years later. The reason? Indifferent and unsupportive parents. DC2 was often chosen to sit on a table with the badly behaved, disruptive kids. I used to question the teachers and they said they may be a good influence.
They also used to get DC2 to help slower children with their work.
DC2 used to get upset when her work was written over, when others wouldn't let her get on in peace.
I won't apologise for being glad that she's not in a school with them now.
