I did my GCSES but I didn’t pass my GCSE Maths, however I have passed it now. But on my past certificates it says A*A*AAAABBBBCC and G in Maths, I was wondering if it is possible to contact the exam boards to take that old grade off the certificates? And to keep my new certificate that says grade C?
Maybe you could just ask for a new GCSE certificate from the exam board your maths is on, and they will give you one with all your grades on including maths? I'm not sure if it would work like that, also it would be expensive. I'd just leave it - you have proof you've got a C.
