^^^ Shouldn't your HSC be 2008, then, not 2009? But anyway.
3U and 4U Math scale REALLY well if you do well at them. I don't do them personally, but I'm estimating that if you get around the high bands in both, and perform consistently throughout the year in not only those classes but all your subjects, your marks will be elevated.
Same goes for Chemistry and Physics, since the three specialised sciences can scale as well. Aim for a mid Band 5 in your sciences at least, and perform consistently in-school for assessments, and you're set.
Standard English ... not sure how that works, but my teacher says it's really hard to get a Band 6 in Standard, so I can't help you there, nor with IPT, but you're doing quite a few difficult subjects so if you get good/excellent results in those and high results in your others, you should be fine for a 92+ ...
Although if anyone wants to correct me, feel free ...
@Forbidden: Exphate's right - teachers from your school can't mark your papers, because they're considered biased.
@Buiboi: I'm inclined to agree - I doubt the tutors actually do the assessments for then, it's probably more of the fact that they have a big, HUGE hand in the quality of the material that goes into it. Good luck to those kiddies who have those kinds of tutors ...
OKAY! My turn at this ... my subjects:
English Extension 2
English Extension 1
English Advanced
Mathematics
Biology
Business Studies
Considering the fact that I went pretty averagely in my assessments (failed some, but meh ... yes, I probably did screw my chances of anything above an 84 ...), and I'm aiming for 75+, how should I aim to do in the exams? Anyone? XD
