I have 3 kids aged 14, 12 and 10. we are due to move to Sydney (not sure which area but i have been looking at Cherrybrook) in April this year.
My oldest son is in the 'gifted and talented' sets at school and although only 14 he has sat most of his GCSE's last year and this year.
I am concerned that if he moved to Australia at his age that he will not be able to pick up the curriculum in time to get decent grades in the Australian exams and that his current UK exam results may no count.

has anyone had a similar experience or can offer any advise? This would be greatly appreciated
