National 5 subject choice column restrictions?

I know my school generally implements the CfE 8 curricular areas in S4:

Literacy (English)
Numeracy (Mathematics)
Modern Languages (French/Spanish)
Social Subjects
Technologies (including Business)
Creative Art
Core RE
Core PE
Elective Choice

Exceptions are made for allowing access to three sciences or two languages/social subjects if so desired.

In my school for fourth year there were just columns, you didn't have to pick a language or a social subject but they were grouped together in a column with other subjects. All schools are different though so the best thing to do is just ask.

I am concerned about the restriction of free choice in s4. I am currently in s3 and I am very worried incase I am forced to continue things like a technology, a creative art or a social subject. Does anyone know anything about if subject choice is a free choice or restricted?

It would be useful to know because I want to do some out of school studying for the subjects I know I will be taking

My current subjects are:
Art
german
chemistry
physics
design and technical
history
biology

(btw next year we have a limit of 6 subjects sadly)

I’m choosing me subject for Nat 5 now in my school there’s is no requirements for Nat 5 apart from maths and English. I’m not sure if it’s the same for all schools
