Sidharaj you must be talking about Bhandup school. This school.is located in Thane and it has ample space. Inside and outside. Secondly it is an CBSE curriculum board. B.S.Bane International School.
It is a pretty good school. I have spent 12years of my school life here. Just one thing, the campus lacks space.
It's an English medium School.
