This report shows the 2017 top student in each HSC subject as awarded by the NSW Education Standards Authority. Students must achieve a band 6 or band E4 result in the relevant subject to appear in this list. Rankings are calculated from student HSC marks in the subject, or, where this results in a tie, from the average of the students' examination and assessment marks.
