When we realised they weren't going to be extended by the school in Math, we got them tutoring.
Any subjects they felt they had difficulty keeping up with, we got them tutoring.
We focus on effort, commitment, and don't be scared to give it a go, and get it wrong, you're there to learn, not to know it all. The only bad mistake, is the one you don't learn from.
They know that if they want something education related, even if not curriculum related, that we'll spring for it. As a result, one is teaching themselves Japanese, and the other, Russian and Korean.
Education as a gateway to success, however they deem to define it for themselves, is promoted.
We have worked hard, from day one, at a very healthy diet, and sleep, and we recognise and support mental health issues.
In short, our kids have had a fairly privileged life, that we have been privileged to be able to provide them.
