The University Handbook is where you can find unit and course offerings and rules to help you enrol. You'll also find important dates for the year and links to other information you'll need to know.
Previous years' Handbooks are available if you need to check on course or unit details for a previous year's enrolment.
What's inside the Handbook?
Use the Handbook to view electives, majors and units for your course. You generally need to follow the course rules which correspond to the year you commenced your course.
To find which units are offered this year and when they are offered, just look them up in the Handbook.
