If a school in Doha has a place for your child, it probably means that the school is rubbish and you should not consider sending your child there. If you find a school that seems to be very good, then it will be full and maybe you will have to wait a year or two before a place becomes available for your child. In the meantime, you will have to send your child to a bad school. By the time your child is finally offered a place at what you hope is a good school, your contract will probably come to an end and then you and your family will have to leave Qatar.
