British Curriculum Schools in Ahmedabad

Hi,
We are considering a possible move to Ahmedabad this year. We have two kids in school, Year 1 & 7. Their school follows the Modified British National Curriculum (GCSE, IGCSE, A/S level, A level). We wanted to inquire about members who may have kids in similar curriculum schools in Ahmedabad.

- What schools would you recommend?
- Schools with, both academic and non-academic (drama, arts, sports, etc.) focus.
- Good student to teacher ratio

Looking forward.

Thanks.
