Make sure you’re meeting your course requirements
If you’re choosing to complete a unit in a session other than Semester 1 or 2, you need to make sure it meets your course requirements and you have satisfied the prerequisites so it counts toward your degree. Check your course rules and unit of study requirements in your handbook.
You also need to make sure you have space in your course. Most full-time students will complete 24 credit points each semester. All courses will let you enrol in up to 32 credit points during each teaching period, so that you can complete an intensive unit that falls outside of the main semesters.
