Crap GCSEs help!

[Blueberryancakes]

Not sure if anyone could help?
i got 4 x GCSEs - CC English, B Art and C in religious studies.

I have also done an NVQ level 2 & 3 in customer service (10 years ago)

I remember having to do key skills as part of both NVQs.

Anyone know of the Maths key skill in the NVQ would be equivalent to a GCSE level C?

thanks so much in advance

What level key skill I think level 2 was equivalent to a A-C and level 1 to a D-F. So if it was the same level as the NVQ it should be fine but some places ask you to redo it anyway
