Places have been filled by now and waiting lists will have been updated. Schools are not back now until beginning of September (by that I mean school offices) and I am almost sure that whatever school you pick, you will be placed on the waiting list. Have a look at schools suitable to your 'requirements', but be aware that the more waiting lists you join, the better chance you have to get a place. But first you need to get here as no school will give you a chance to even join the waiting list if you are not physically in Qatar.
