Computer Science GCSE cancelled at school

[ThisAintLegit]

My child's school has decided not to teach Computer Science any longer. No formal reason was given but it was clear that the teacher was very poor (my kids have had this teacher and agree) and results were an issue.
We were very disappointed but were told that DC could still study it at A-level elsewhere with strong maths which they have. We've since learned that this is impossible as all the 6th form colleges reasonably expect a 7+ at GCSE.
I don't know what to think now. DC is entering year 10 and can't move schools, but is talented at computer science. Someone suggested we get a tutor and enter as an external candidate. But how would the project work get marked as an external candidate?
Is there any option we may be overlooking?
Thanks everyone for getting this far.

forget the GCSE, you don't need it for A level or even for a computer science degree.

Get coding, learn python out of school. CodeAvengers.

A good maths grade and evidence of interest/passion is more important than having studied CS.

Lots of schools don't teach it. Impossible to get decent teachers.

I also think universities will be less likely to bend the rules for women? I admit I have no evidence for such a sweeping statement grin

i think the opposite actually, they are DESPERATE for girls on these course.

look at smallpeicetrust too, cyberfirst.

Everyone else has beaten me to it, you don't even need CS at A Level to do a degree (maths is far more important!) so I wouldn't worry about the degree. Start looking at online courses or summer courses for next year mentioned above (Smallpeice, Cyberfirst etc).

Same thing at my dds' school. No computing teachers so no GCSE offered. But, if they want to do it at A Level, they only need a 7 in Maths.
