GCSE and SEN

[ChristmasFlary]

Yr11 DS currently not doing at all well despite school giving loads of support and input.

He is taking maths, English, science, art, history.

Currently predicted U/1 for science.

I really don't see the point of him sitting this exam. He can't do the homework. He is often missing from class due to disagreements with the teachers and gets detentions. The thought of putting him through the exam and all the anxiety amd stress that causes just seems completely pointless when he isn't going to even get a decent mark.

Does anyone know if he can drop this "compulsory" subject?

GCSE grades 1-3 (old terminology G-D) are level one qualifications
Yes, that's what I said.
@Shiney, could you clarify what is the meaning/ significance of those various qualifications? It is confusing and difficult to understand how they stand vs GCSEs. for the purpose of further education.

How / what qualification exactly one can ask to enter DC into in such situation to enable DC to pursue GCSEs at Level 2 in the next step?
I don't mean resits ! I mean properly having two years of GCSE tuition at level 2 after having sat the level 1 exam?
