Below is the list of the best HSC students in 2018 ranked in order of their total number of subjects awarded.
A subject award can be either a Distinguished Achiever award or a Subject Rank award (top place in subject).
Where students have equal numbers of subject awards, those with an All Rounder award are ranked higher. As additional tie-breakers, Subject Rank awards are ranked by their place value and they are also ranked higher than Distinguished Achiever awards. Where all of these measures are equal, entries are listed alphabetically.
Note that these rankings are calculated using only the published results for 2018. A student's awards from any earlier years, if any, are not not included here.
