Jesus Christ, this thread.
Your daughter has done ONE TERM of A level study. An E now is a pass and might translate into a C or even a B by the end of the course. Naturally every fucker on Mumsnet has teens getting 6 A* at A level and having Oxbridge begging them to come in, but the real world isn't like that. Only you, she and her teacher can say, based on her prior results, whether she has a technique problem, a revision problem, has been very disrupted with covid etc, or whether she is doing ok.
My son has got 2 Us so far in one of his subjects. He hasn't quite got his head round the way he needs to present information in order to score, it's a new technique. I am not extrapolating from that that he will get a U in his final A level exam, although I accept it's also unlikely he'll get an A. He has learned that he has to put more work in to revision (of course he didn't take his GCSE exams, which hasn't helped) and will get the technique eventually.
My older son had a nervous breakdown during his sixth form, had to drop one A level completely and got CE for the other two. You know what, he still had two A levels and the fact that he had those two A levels is a far greater testament to his resilience and determination than if he had sauntered through 4 A* with ease.
Sometimes the people on here seem to live on a different, problem free planet, I swear.
