We're not even at GCSE Y11 yet. Thats next year ...
But unless your DC is very academic and dead set on university and/or can easily afford it - does it really matter if they get 7s or 5s or 9s. I appreciate trying to get above 5s are important as are a door to things post-GCSEs but apart from that?
And of course its good they do well and do themselves justice for its own sake. But otherwise is it really that important?
I'm not even sure I would be advising my DS to go to University. Who needs £60K worth of debt - £27K for the degree, at least £30K living expense? Unless you are very committed to studying for a particular reason.
Anyway, I'm writing this as I know I've been getting a bit uptight about end-of-year exams and the coming GSCE Year 11 so trying to get some balance. In the scheme of things isn't it worth remembering there are more important things in life, and sometimes isn't it easy to forget?
