My second daughter is like this. We are in Australia so no GCSEs but she’s just finished an exam block. She’s in year 10 and it’s supposed to be a more “fun” year - a student has to do maths/English/some form of science and a humanities but there’s encouragement to try a range of subjects before committing to 6 for years 11/12. It hasn’t been fun though, with the subjects she cares about she’s very hard on herself about.
It’s a very academic, selective school and in the core subjects they grade very harshly; last term only 10 of the 200 in her year were awarded an A grade (of any kind) for English. A- is >80%, A is >85, A + is >90. To get an A in maths you have to answer the A questions which are supposed to be complex questions that aren’t familiar.
she has always been smart and done well but this year, suddenly, grades really matter to her and she’s actually studying for exams, which she’s never done before. She’s topped the year in 3 subjects so far, including physics and chemistry but isn’t as strong in maths, as in she’s probably in the top 10 in the year. She wants to do physics at uni.
a few weeks ago DH and I were at work and she went to the office and called in tears, saying the specialist maths exam was horrible, she got loads wrong, she needed to go home. We are both doctors, with patients so couldn’t take her so she booked herself into the well-being room at school and stayed there for the afternoon, sobbing with the therapy dog.
As it turned out, she got an 88% which is an A and the cause of the angst was getting two “easy” ones wrong at the beginning of the paper and she wasn’t able to let it go.
Last week she had the rest of exams, including core maths and maths extension and I was a wreck waiting for similar phone calls (maths extension is hard) but they didn’t happen, thank god.
My theory (as someone who has done zillions of exams) is that if she’s embarking on a maths heavy career then she’s going to have to work this out for herself, to some extent. She’s learned from the first term that she’s better doing swimming training in the morning before a hard exam, as it helps with her focus. She’s worked out that in a 6 mark extension question the final answer may only be worth 1 mark so no need to worry if the answer isn’t cornet and she’s working out how to pace herself for longer, harder exams.
My response to her catastrophising has been “let’s just see” and basic looking after her stuff - food she likes, cleaning her room for her, making sure she exercises but I do think, with children like these, they need to find their own way through.
