One of the advantages of the Duolingo English Test is that you can choose your own testing environment and testing time. There are a few general guidelines to help you consider where and when to take the test.
Take the test when and where you feel most comfortable. This doesn’t have to be in your own home, as long as you can ensure privacy.
You don’t want any background noise to interfere with your responses or distract you.
Make sure no one disturbs you. Tip: put a “do not disturb” note on the door!
The proctors will need to be able to clearly see you throughout the test, so make sure the room is not too dark.
