Can anyone tell me how the secondary school system works in Australia and/or New Zealand, please? In particular, I'd like to know what is their equivalent to the UK's GCSEs and A levels and at what age do the children start working for them and actually finish the courses. Maybe there is also an option to do an International qualification in the subjects so that it's easy to compare it to GCSEs and A levels when you go home (to the UK) again? Any advice welcomed. Thanks.
