After your certified test has been graded and reviewed, a notification of your results will be emailed to you at the email address provided during registration. You can log in to the Duolingo English Test website and scroll down to "My Tests" to view your complete certified test history and results.
Practice test estimated scores are only displayed at the end of each practice test session. They are not stored in your account. Once you close the window displaying your estimated score, you will have to take the practice test again to view your estimated score again.
