Perceptive comment DZ - because maths is one of the specific issues. She'll probably get an A at GCSE in it because she's basically a bright kid, but she has no natural aptitude for it, something that has been borne in on me through helping her revise. In terms of utility, I (who accumulated more than one maths A level and work in a numerical scientific discipline) would push her to do maths A level because I know how integral to so much of life maths is. In terms of pleasure, I would tell her not to, having seen how painful maths is for her.
I didn't name subjects in the OP because I was more interested in the principle of education-for-jobs versus education-for-its-own-sake. But as it happens, the specifics are that she will almost certainly do English, History and Biology. The question is what the fourth should be - maths for utility? chemistry so that with biology it keeps some scientific/biological/medical options open? Or French or music as her strongest subjects on the "do what you enjoy" principle?
