English Extension 2 has a value of 4 units, divided as follows:
- English Advanced - 2 units
- English Extension 1 - 1 unit
- English Extension 2 - 1 unit
Unlike Mathematics Extension 2, English Extension 2 students still take English Advanced and must still sit the English Advanced HSC exam.
In terms of the notion of the best 2 units of English, this can come from any English subject and in different combinations, for example:
- 2 units of English Advanced
- 1 unit of English Extension 1 and 1 unit of English Extension 2
- 1 unit of English Advanced and 1 unit of English Extension 1 or English Extension 2
Of course, the above possibilities will depend on the student's subject selection as well as their overall performance in each subject.
I hope this helps!
