Mixed reviews on GEMS World Academy in Dubai?

We are updating our guide to schools in Dubai and would like some imput from parents on the GEMS World Academy in Dubai - it would be a great help if parents who have or have had children at the school could write some reviews. We have seen mainly good reports on some of the (many) other GEMS schools in the region, but have heard mixed reports on GEMS World Academy in Dubai. What are the main nationalities of kids in the school, how large are the class sizes, what are the facilities like at the Academy. How good are the teachers, and what is the main nationality of teachers? How much home work is there and how do the fees compare with other schools. 
Many thanks in advance.
