Are these good A level choices?

So, one of my previously asked questions were to do with finalising my A level choices and I've finally decided what I'm going to do which is:
- Maths
- Further maths
- Psychology
- Sociology

I've chosen these subjects because I love maths and I'm good at it and want to continue studying it. I'm interested by the social sciences/humanities and feel like I'll find them enjoyable.

After A levels, I'm thinking to do a maths degree in order to become a secondary school maths teacher.

Are these subjects a good combination? Or do they not go well together?
