Your test could not be certified

Very frustrating and inconsistent experience.

I took the Duolingo English Test and carefully followed the setup instructions. During the setup process, the system checked my phone/secondary camera placement and explicitly indicated that the setup was acceptable, so I proceeded with the test.

I felt that I performed very well on this attempt. However, after completing the entire test, I was told that my test could not be certified because of a verification issue.

What I find particularly frustrating is that the system allowed me to proceed after checking my setup. If the camera placement was unacceptable, the system should have identified that before I spent the time completing the entire test.

As a test taker, I followed the instructions presented to me and relied on the system’s confirmation. Having the test rejected afterward makes the setup-checking process feel unreliable and creates unnecessary stress and wasted time.

Duolingo should improve its pre-test verification system so that candidates are clearly informed of setup problems before the test begins.

Review

Before launching a test, check how well-made it actually is first. There is no point in your test if taking it a second time in the same week can give a completely different result. This is not English proficiency, this is just a "guess-the-word" crossword puzzle. On top of that, it is graded by AI, and it is so linear that the algorithm simply counts words like however, firmly believe, beneficial, and facilitate as better English proficiency. And I have no idea how universities even accept tests like this.
