I guess you are moved now, but for anyone else reading this thread there the British system equivalent which is the Cambridge system. In kwazulu-natal there are 3 known schools teaching this curriculum. A new school, Reddam House is due to open in 2017 also teaching the Cambridge curriculum (IGCSE, As and A levels) Other provinces esp JHB there are more schools
I live in Ballito, near Durban if you have anymore questions
