My Mum couldn't have helped me despite going to a grammar school herself. She hated it, the uniform, the hat, the indoor shoes, the cooking classes and needlework by hand. She left school at 15 which was the leaving age back then. She hated every second of school and I am not sure she even left with one qualification. My Dad on the other hand went to a technical college and got HND qualifications but he worked abroad for weeks at a time so was hardly home. Everything was left to school to teach us and I had no help with homework or revision. I got by and went to uni but I wished I had had the same support Dh had when he was growing up (middle class, SAHM)
So I did support my children with their homework but more on the how to research and how to put an answer together not the actual doing. School also taught the parents this too, we were invited into school with our children and sat through an elaborate play put on by the theatre students, honestly it was amazing. This was a state school. It was all about which source you could trust and why you should corroborate your sources.
Yes I knew what books they were studying for GCSE because again school invited us in, talked us through revision techniques, pointed out the important things of what sort of answers get the best marks. They made us do some of the work too that our children were doing. They provided all the revision books for free and used them in class alongside their work. The school was outstanding and had an incredible Progress 8 score. I also put scaffolding in place to enable them to succeed, if they forgot something I would ask how do you think you would remember it next time? Teaching them to solve their own problems never jumping in and telling them.
All this helicoptering just meant that Dh and I were a sounding board for things like A level choices and uni choices because we were the ones driving them to open days, looking over their spreadsheet of uni choices, grades. Both my children went to uni, both have excelled, Ds landed a graduate job all by himself, no input from us at all. It doesn't all mean your child is incapable of doing things by themselves. We are just here to talk to as both Dh and I went to uni.
Plus a lot of parents will have put their child through the 11+ probably with tutoring and then that school experience is probably very different from your average state school. Mine had mixed sets for language GCSE and it was a fucking disaster. Even though the school was incredible, this was hard for mine.
I turned to a specific teacher on MN for help and she was incredible. Some children are not mature enough to see the big picture, the playing field isn't level, there are parents paying huge amounts of money to ensure their child has a better and more rounded education than mine.
