For the Higher School Certificate, there are three Board Developed mathematics courses for study as Preliminary Year courses: (in increasing order of difficulty) Preliminary Mathematics General, Preliminary Mathematics, and Preliminary Mathematics Extension.
There are four Board Developed Courses and one Content Endorsed Course (CEC) for study as HSC Year courses: (in increasing order of difficulty) Mathematics General 1 (CEC), Mathematics General 2, Mathematics, Mathematics Extension 1, and Mathematics Extension 2.
Students of the two Mathematics General pathways study the preliminary course, Preliminary Mathematics General, followed by either the HSC Mathematics General 2 course or the HSC Mathematics General 1 course.
Mathematics consists of the courses Preliminary Mathematics and HSC Mathematics. Students studying one or both Extension courses study the course, Preliminary Mathematics Extension, before undertaking the study of HSC Mathematics Extension 1, or HSC Mathematics Extension 1 and HSC Mathematics Extension 2.
