Religious Studies GCSE Short Course

With exams coming up in about 3 days, I'm pretty much projected to get straight As/7s/D2s, with even a good handful of A*s in there. The only issue is short course RS, where I'm basically screwed (for me at least, I consider a C to be a fail). I need to know, would it be any bit impactful long term (not short term, since my sixth form won't accept it regardless) if I end up getting a bad grade on it? Especially since it's a short course, does it have ANY value besides being 'half a GCSE'?

I think as long as you pass will be fine. If you are taking RE in A level you might need B or above I think
