The Duolingo English Test is fast, modern, and very different from traditional exams like IELTS or TOEFL. If you don’t understand how it works, you can easily lose points—even if your English is good.

So here are 27 essential things you need to know about the Duolingo English Test in no particular order.

1. Know All Question Types
