Just to help with choosing subjects, methods is closest equivalent to mathematics. Mathematics is the highest 2 unit maths you can take (just no extensions on top). Maths syllabus varies a lot, my yr 11 VCE friends do very different topics in methods. For English, even though you don't do Lit, you'd prob be up to doing English Adv. Then the other subjects? Well you could pick 3 other 2u subjects then for the minimum HSC load of 10 units. You should check if you should do Yr 12 bio again so it can count for your ATAR-I don't think you can mix VCE and NSW subjects in calculating ATAR, as the states use a bit of a different system to obtaining the ATAR.
