ATAR calculator says that HSC marks of 93 in all those subjects will give you a 97.5 ATAR.
However, if you're basing the idea that you'll get 93 in your subjects on the fact that you got 93 in your subjects as internal marks, then I would say that this perception is ill-informed. I would be putting more effort than you think is necessary. HSC exams are likely going to be marked to a different standard to how your school teachers mark, especially if your school is historically low performing. E.g. my school/trial marks as real HSC marks would hypothetically round out to an ATAR around 99.8, but my actual HSC marks led to an ATAR around 96-97.
Also, make sure that your internal ranks are like the best they can be, because good internal ranks will help minimise the effects of HSC exam stress which can actually really make or break your results.
With that being said, any combination of subjects can yield your goal ATAR. Yes, scaling matters to an extent but it should never be the sole concern of your subject choice. Your concern should be on whether you like the subject enough to study it for 1-2 years. i.e see numerous cases of people getting max ATAR with dogshit scaling subjects that they actually enjoyed studying.
