Sounds very familiar…
Have you tried asking the teachers? You aren’t going to get anything through email as their not likely to sign off the end of their own careers. You might be able to get something out of them verbally. They probably aren’t the happiest of bunnies if its a target oriented environment (experience).
Personally I don’t believe you should stop her from doing them. I too always have a thing for people getting something they haven’t earned/deserve. However it’s life I guess!
Think of it in another way? Sounds like your daughter worked really hard recently. Have her do them under the least amount of pressure possible, she’ll do really well and you can reward her. She’ll have proof of how hard she’s worked.
It will set her in good stead for the next 10 years of her sitting exams every summer (I tried looking for an emoji to represent this but there isn’t one for hysterical insanity). Trust me she’ll need it(the recognition that is).
