Hi, DC has an offer for the sixth form at Graveney School in south London. It seems like a great school but we don't know any parents with children there so have no idea what it's really like. A few questions come to mind: are the sixth-formers put in ability sets or do they all mix together in class? Do external students fit in OK? Has your DC done well there? (And anything else plse). We've got to start thinking about this now so any help much appreciated!
