My Australian/British friend (she has lived in the U.K 20 years her kids are all at grammar schools).
However, she is adamant that her Higher School Certificate (HSC) qualification's are superior to my A level ones. She also suggests that Australian Selective High schools are more selective and difficult to access than many English Grammar schools.
She was also 'goading' me about the significant number of Alumni of her school, Sydney Girls High compared to the number from mine, Newstead Wood. This is despite the two very famous recent ones.
Therefore, is the standard required to get high grades in the HCE, equal or greater than that of A Levels.
