Re-enrolment is the same process you went through to enrol in units for your first year, except you will be enrolling in more advanced units.
All students at Bentley campus enrol in units online using eStudent (via OASIS). ReEnrolNow! is a special channel that appears in OASIS during the re-enrolment process that will help you through the re-enrolment process. You can also read detailed instructions in the eStudent help.
