Whether you consider your marks to be good depends on your own standards, including your ATAR goal. Generally speaking, CSSA papers can be considered slightly more difficult than HSC papers. Based on this, it would be reasonable to suggest that your marks in your Ancient History, English Advanced, Modern History and (to a lesser extent) Biology CSSA trial exams are good.
Ancient History and English Advanced appear to be your best-performing subjects. This is a positive indicator in terms of your performance in your HSC exams of these two subjects. It is therefore important to ensure that you keep preparing as you get closer to the HSC exam period, which will hopefully lead you to favourable performance in both subjects, consequently increasing your chances of reaching your desired ATAR.
Regarding Modern History and Biology, it also seems like you have the potential to perform well in the HSC exams of these two subjects. However, your marks could indicate that there might be areas of improvement to address. You may therefore wish to consider revisiting and emphasising any concepts that you may not be fully confident with as part of your preparations.
On the other hand, Mathematics Advanced seems to be your lowest-performing subject. Given that you are taking 10 units, it is crucial to prepare for your Mathematics Advanced HSC exam to the best of your abilities so that you can ensure the best possible performance in your exam, especially because it will count towards your ATAR. You can do so by seeking clarification with concepts that you may not fully understand as well as completing a range of practice material, including past HSC exam papers, trial papers and textbook questions.
I hope this helps!
