Just been reading through some old posts and found yours unanswered !
Did you decide to go for St Olaves test ? How did it go for your son? (Good I hope!)
Its a while before I go through all of this but i'd be interested to hear of your experience.
Was St Olaves recommended to you ? I presume you would only put them in to sit their test if the primary school gave you a recommendation, Is that how it works ? Or do you go by Kent/Bexley results?
Just trying to get a feel for what's out there and how the system works.....
