I think you are quoting me there - so I'll answer anyway.
Why not students? That's the word I would use. Children is certainly not a word I would use about an 18yo (which is how old many A level exam candidates are).
You ask how much of what I mention is unseen, in exam conditions? All of it.
None can be cheated using online resources as they have no access to the internet in an exam room, whether that is the written exams or the speaking exam.
The only element prepared in advance is the candidate's IRP - research project - so they can learn their two-minute speech. But that counts for 5 marks out of a total of 60 for the speaking exam.
The original essay cannot be drummed in as no one can be sure what the subject will be. Of course you practise essays in class and as HW on the main themes and you learn and revise phrases and vocab that are relevant to the film and book. But the exam essays are not corrected as coursework by the teacher - because, yes, it's an exam!
not sure what you mean by "passes Oftsed" btw - as far as I know Ofsted does not assess whether someone has passed their MFL A level.
How is it remotely possible for a native French speaker not to be able to write a decent few paragraphs on strikes?
I mean I have to say, I am not sure, as a native English speaker, I could off the top of my head write or speak several paragraphs about strikes in the UK, adducing facts and figures of when, why, how many people, what effect it had on the strikers and what was the result. Could you, honestly?
