What PTE score do you need for the University of South Carolina?

The Graduate School page says official scores must come directly from the testing service, that copies are not official, and that language test scores are valid for two years. Its list of codes gives the PTE recipient simply as "University of South Carolina". Neither page mentions PTE Academic Online or PTE Core.

For comparison, both pages ask IELTS 6.5 against PTE 53. The graduate page specifies IELTS Academic.

USC's English Programs for Internationals offers undergraduate conditional admission to applicants who meet the academic requirements but not the English minimum, which it gives as PTE 53. Conditionally admitted students complete the right level of English courses, or meet the requirement, before taking university courses. The undergraduate page says to indicate interest in EPI and conditional admission on the application and to apply to EPI directly.

Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your USC programme page and in your offer letter, so check it there before you book a test.
