Ideal Indian School is very well known for providing good education...what it lacked was a good infrastructure, but now they will be opening the new Ideal Indian School INSHALLAH which is has amazing and will be opening in abu hamour probably by September, I guess.

I would say that the new Ideal Indian School would be the best choice because of the following reasons:
It is Economical
Provides with good education with few teachers who are really good. To be precise, I wouldn't say all teachers good but yes, there are few very good teachers.
Has a good infrastructure.
