DS is doing AS Further Maths. Based on performance to date his teachers have predicted a C which is much lower than he was hoping for and I think he can do better (got 8 at GCSE & A in FM GCSE equivalent). He hasn't been slacking - I think its more a question of being a bit slapdash. (I did Maths myself to uni level so know a bit about it although a long time ago).
I will talk to his teachers but tbh they aren't very user friendly so I wondered if any Maths teachers on here could help with some strategies to improve his grade. I know that practice will help but I think the way he's practising is also key.
