@Araminta1003 I think grammars, while hamstrung by budget, are dealing with a vastly different parent body. I am in awe of how DD1's (and formerly DD2's) comp managed to deal with the hugely disparate needs of an entire cohort - but most of the money and time did have to go on the needs of those struggling at the bottom.
When it comes to helping the children I did so much more with DD1 because Covid and the weird decision that they should do triple science in the top set in the same amount of time as combined for everyone else meant huge, huge holes.
Also no music teacher for much of it. DD1 had a science tutor, and help with maths from her grandma, and I did absolutely loads on RE and Latin lit. Without it she wouldn't have covered the whole course. Her year did not do well, and the school has upped its game since and put in extra periods for Year 11 only at school. DD1 did get a good spread across the board - all 7-9 - but definitely would not if she hadn't had parental input.
DD2 does not have tutors - which given we pay a contribution towards her education at music school is just as well! She has actually cost us less than her state schooled sister though because of this.
I normally don't get to help her at all as she's away at school - so this week is my only chance. It's a bit of a bonding opportunity too.
And no, my parents did nothing with me and my sister (state comp) - we both did well and went on to Oxbridge. Mum and Dad were surprised to be honest.
They had a tutor for my brother who really floundered, even with the help. But the content was so much less then.
