Favour needed: any ex Kimberworth students?

Hi all. My partner needs to track down her GCSE grades, but with the school shut down and no sign of her certificates, she needs to know which exam board she was with in order to verify what she got.

Any ex students from around 1998 still got their certificates for Maths and English and can check which exam board it was?

Massive long shot, I know, but thought it couldn't hurt to ask.
