This is a bit tricky. My DS has been asked to start preparing for the spoken assessment of the Eng Lang GCSE. This week he was told that the school has moved these forward and they will be done in December, rather than January. His class was asked in July to start initial preparation over the summer holidays. Their mocks are at the beginning of November, by the way.
Today I was talking to a good friend and asking what her DS was doing his presentation on. She had no idea what I was talking about. Went home and asked him, then text me to say he hadnt a clue either, so it had caused a row.
Her DS is same set as mine, but just a different class, with different teacher. My friend isn't very switched on about academic stuff (she left school young and has a successful career in catering now) and has a habit of assuming her poor DS is always at fault and tends to blame him for stuff unfairly; he is quite laid back and his attitude does wind her up. Annoyingly it's often me who inadvertently "causes" their rows! My DS does talk to me a lot about school so I tend to mention things in conversations with friends, and some of them respond, but this friend nearly always goes back and has a go at her DS if she doesn't know what I'm talking about!
So what, if anything, should I do now?
I'm quite concerned if his class hasn't been prepped at all for this presentation: it means that the other class has had eight weeks more time on it, which doesn't seem fair. Should I encourage her to contact the school about it? She does rather have the opinion that the school is the one responsible for everything to do with education and assumes they will do everything right and in her son's best interests. Perhaps I am a little more cynical 
I am very aware that this summer's GCSE students are a bit of a guinea pig year and that teachers are only human and do make mistakes. I hate the thought of my friend perhaps thinking that I patronise her by being a bit more clued up about current education stuff (I'm interested, I don't currently work so I have time to spend on it, and I'm quite anxious about my kids not making opportunities for their futures), I really truly want all the students to have a fair chance, especially my DS's mates, and it's hard to sit by and not say anything.
Sorry this is so long! Thank you for your advice
