Sherborne which is a very good school in the UK I know, but here in Qatar the students' composition is a problem. It is one where spoiled rich children with bad habits and manners conglomerate. This is due to the facts of being so overpriced and of its location; it would attract mostly these types. Remember; your child will learn more from his peers than from his teachers. On the other hand DESS is a very good school but your child will not benefit from the international mix of students as DESS is made up of mostly British students.
