Check the list of units supported by the PASS program and sign up for a session time that suits your timetable.
For most units, the PASS program begins in the third week of semester, and you can sign up during week two. Look out for announcements in your lectures or on Blackboard/Moodle about when to sign up for PASS.
If the sessions are full, you can request to be put onto a waiting list by contacting a PASS coordinator
