What level of English are you taking? In my estimate, I set English as English Advanced.
Considering all the information that you have provided, I believe a 92 ATAR is achievable with these ranks. Your ranks in Mathematics Advanced, Japanese Continuers and Japanese Extension are favourable and I believe they are consistent with your ATAR goal. Economics is probably the least favourable rank, although I don't believe the effect this would have on your ATAR would be significant enough for your estimated ATAR to drop below 92. Specifically, you could be looking at an ATAR in the low to mid 90's region, approximately 93. Despite the lack of band 6/E4 data in terms of Japanese Continuers and Japanese Extension, I believe your ranks are high enough to achieve a band 6 and band E4 in Japanese Continuers and Japanese Extension respectively. You should keep in mind that you are yet to sit and complete the HSC exams across all your subjects, all of which are worth 50% of your HSC marks in your respective subjects, meaning that they constitute a great opportunity for you to maximise your chances of reaching your desired ATAR by doing your utmost to ensure favourable performance.
On another note, it's good to see some NSL students around here. Stay tuned and be ready to share your thoughts regarding the Japanese Continuers and Japanese Extension HSC exams!
I hope this helps!
