In Melbourne, the qualified scores can be divided into P/C/D/HD, with more than 50 points passed, and the number of make-up exams and subjects are not limited. Some schools don't offer make-up exams (such as some subjects in the University of Sydney).
Subjects with a score of 40-49 can be retaken (previously, only two can be retaken). If the score is lower than 40, the course will automatically quit. If you are not satisfied with your grades, you can also choose to drop out of the course, which is not included in GPA and WAM. If you are not satisfied, you can pay.
