Looking at the education increase, it's not enough.
The main English based curriculm schools in Dubai have fees higher than the Emirates limit and in my case will cost a months salary each year. An equal or better private education in my domicile didn't even come close to the fees charged here. The educational allowance has slowly crept away from the fees in reverse gear. A consideration for a new joiner would not be "what do I pay this year" but what do I pay over the entire period you are in Dubai.
The schools in Dubai that I have had anything to do with are overall very good. I have to admit that Emirates conditions are not keeping pace with true educational costs.
By the way, I'm only talking school fees. You want to talk extra curricular activities......
