No problem! Based on this information, I believe that your current performance is consistent with an ATAR of up to 94.5.
Your performance in Mathematics Advanced and Biology is of a high standard and is highly likely to make a positive contribution to your ATAR. Because of this, it is important that you maintain your optimal position in Mathematics Advanced and your favourable position in Biology. You may also have the opportunity to improve your rank in Biology which, if you do, would further enhance the contribution that this subject would make towards your ATAR.
Your performance in the rest of your subjects is not of a low standard by any means. However, achieving your ATAR goal would require you to improve your position as much as possible in each of those subjects so that you can maximise your chances of reaching an ATAR this high. This is most importantly applicable to Chemistry and English Advanced, with the latter being the only subject that will always fully count towards your ATAR, as opposed to your other subjects, where Mathematics Extension 1 may halve the contribution of one of your other two unit subjects, or may not count towards your ATAR altogether, depending on your overall performance.
Of course, it is important to keep in mind that such estimates are not decisive. In fact, I believe that you are on the right track in terms of achieving your ATAR goal. Hopefully you will be able to perform at a higher standard in your upcoming assessment tasks/exams, which will ultimately bring you closer to your desired ATAR.
I hope this helps!
