I don’t understand why you ask this. What does it matter re: the quality of local schools?
If you can’t afford the intl’ schools which are the only ones that could cater to your kids that will be in Middle School ( not Senior School, btw) then u have ur answer.
What alternative do you have? what kind of answer are you looking for? There is no magical solution as far as I know. The only option left is the what I suggested, since u are determined to move here.
