Hi Sarthak, Please check https://immi.homeaffairs.gov.au/change-in-situation/study-situation regarding course changes. The English proficiency tests that are acceptable for student visa purposes in Australia are:
- International English Language Testing System (IELTS)
- Test of English as a Foreign Language internet-based test (TOEFL iBT)
- Pearson Test of English Academic (PTE Academic)
- Occupational English Test (OET)
- Cambridge English: Advanced (CAE)
Please note that the specific English language test requirements may vary depending on the type of student visa you are applying for and the education provider you are planning to study with. It is best to check directly with the education provider and the Department of Home Affairs to confirm which test is required and the minimum score required. Thank you for the question and best wishes.
