What Duolingo score do you need for the University of King's College?

Applicants should arrange for test scores to be sent directly from the testing agency to the Registrar's Office, University of King's College, 6350 Coburg Road, Halifax, Nova Scotia. The page gives no validity period.

For comparison, the same page asks for IELTS 6.5 overall with no band lower than 6.0.

If you studied full-time in an English-language institution for three years or more at secondary level, or one year at post-secondary level, you may not need to submit proof of English. International high school results, such as IB English, can also count at the levels listed.

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