Will this GCSE grade ruin DS’s future choices?

DS did GCSEs this year. One of his grades was much lower than he has ever had in previous assessments. He got a 5 but has never had less than a 7 in tests from school and even his teacher for this was subject was puzzled. We did query it with school but there’s nothing we can do as JCQ signed of their procedure for GCSEs etc. His school took a very tough approach to GCSEs no mini assessments, basically as close to GCSEs as they could have been.
He got 7s and 8s in all his other subjects but typically the one he wants to do at university is the one he got a 5 for. He’s doing it for A’level and his teacher said he’s confident he can do well in it but I’ve been worried that university will look at his GCSE grade and reject him. What do you think?

Are you going to answer the question about taking the resit, OP?

So I am assuming it's either a humanity or something slightly more off the wall like comp Sci. I believe Cs is tough to get a good grade in anyway. History or geography, I would want to look a bit more at where he went wrong in the GCSE. If it's MFL I would say a rethink is in order. Or yes, resit, why not?

@KaptainKaveman we’d not actually considered this. School said GCSEs weren’t being used this year for predicted A’levels and so he wanted to focus on those if GCSEs weren’t going to hinder his getting into university.

[quote Blownawash]@Seeline that’s depressing. He got 8s for the three sciences, both English and maths.[/quote]
So if it's not a core subject he'll probably be ok. If you don't want to tell us the subject, have a look at some of the uni websites for the entry requirements for the course he wants to do. Should give you an idea.
