Hi
I have a friend who has a daughter due to start this school in September, and she is very happy about it!
It is British Curriculum not Indian.
Escape my kids are at JESS too!
The GEMS schools are very nice, my children are at a GEMS school for summer camp at the moment, and from what I have seen of the school, it is very well equipped and has fab facilities.
What you have to remember about schools in Dubai (except for about 2 or 3 non profit schools) is that they are businesses, and the GEMS schools are big business, and some people do seem to have a problem with this.
From what I have seen of the schools, and I have a few friends with children in GEMS schools, I would be happy to send my children to one.
I would take the places you have been offered, as the schools are now finished for summer here, and it will be difficult to get the children in anywhere else before September.
You can always check out other schools once you get here.
Sorry, maybe you are already in Dubai, but somehow I didn't get that from your post?
