HSC written exams began on Thursday, October 17 with a compulsory English paper, and finish on Monday, November 11 with papers for Design and Technology and Textiles and Design.
NSW Education Standards Authority (NESA) acting chief executive officer, Paul Martin, said scheduling the 18 days of HSC exams is a complex logistical exercise involving around 77,000 students, 123 exams and 750 locations.
"The timetable is designed to provide a schedule which is as fair and equitable as possible to ensure all students get the opportunity to do their best in their written exams," Mr Martin said.
To develop the timetable NESA follows rigorous procedures to provide sufficient breaks between exams for frequently combined courses, and to minimise the number of students with two exams scheduled at the same time.
NESA has identified and made alternative arrangements for the very small number of students who have conflicting exam times.
Also NESA needs to enable all exams to be marked and students to receive their results from 6am on Tuesday, December 17.
Results from the HSC exams account for 50 per cent of students' marks for the internationally recognised credential.
