Ceebs explaining this again... But in summary many including myself have gotten 90+ in 400+ schools. In the end it is your school's cohort, and not the actual school itself that will affect you.
Easiest way of explaining this is in MOBA terms, you have your carry, your support, feeder, pusher, escaper.
Carry- The very high achieving person mostly found in the higher ranked schools that will carry your moderated assessment marks if you don't come first. Very few in lower ranked schools.
Support- Gives notes/resources to class, otherwise not accessible in a lower ranked school.
Feeder- The guys that get the lower end of the marks and are not even considered outliers, that may drag your moderated assessment marks down. Again mostly found in lower ranked schools.
Escaper- 1st or equivalent value in internal rank that can get a free pass if they don't do aswell in the external exam.
Ehh theres a few others, but there are many many things that will affect your HSC marks, so there's no real disadvantage of being in a higher ranked school, but you can still get 99.95 in a lower ranked school, it's just a little bit harder without your hard carry's
