For entry into most USC undergraduate degree programs, you need to have completed a minimum level of education similar to successful completion of Australian Year 12 with good grades.
Further studies, for example, a semester or more at college or university, can also be considered for entry and may give you credit transfer towards a degree.
Some examples of upper secondary qualifications and a guide to the minimum grades that USC will consider are listed here. These are minimum requirements and do not guarantee entry. Some programs may require higher grades. Alternative qualifications may also be considered on a case by case basis.
If your qualification (grouped by country) is not listed, send the qualification transcripts with your application form to the International Office for assessment.
