About the Test
What is Duolingo?
The Duolingo English Test is a computer-adaptive test you take at home, on your own computer, in about an hour. Results are typically available within two days and the fee is a fraction of traditional tests.
Its adaptive questions adjust to your level as you go, and it ends with a video interview and writing sample that are sent to the institutions you choose. Hundreds of universities now accept it, and its popularity keeps growing precisely because it is fast, affordable and convenient.
Our four-week programme focuses on format mastery: understanding the adaptive flow, drilling integrated tasks and rehearsing confident, natural self-recording.
