I don't think there really is much. I've tried to look in places because I'm doing AQA French GCSE, but don't know how to revise. I guess all you can do, is look on bitesize and stuff.
There's not much stuff out there for listenings, you can get tapes from AQA but it's probably a bit late now. You could ask your teacher? I think the videos on this website are good, it's not specifically for GCSE but has the sameish topics, and it's about getting used to hearing spoken French really. http://www.bbc.co.uk/languages/french/mafrance/
