Duolingo Exam Mistakes That Lead to Disqualification

Many students complete the Duolingo test but never receive a valid score.

Instead, they see:
“Your test could not be certified.”

Why does this happen?

Because even small mistakes can lead to disqualification.

Let’s understand what to avoid.

1. Looking Away from the Screen

  • Frequent eye movement raises suspicion
  • Looking left, right, or down repeatedly
Why it matters
  • AI assumes you may be using external help

Keep your eyes focused on the screen at all times

2. Background Noise or Talking

  • Voices in the background
  • TV, music, or conversations
Impact
  • AI flags possible assistance

Even small sounds can lead to disqualification

3. Someone Entering the Room

  • Another person appearing on camera
Result
  • Immediate violation of test rules

You must be completely alone during the test

4. Using Phone or External Devices

  • Checking phone
  • Using a second screen
Outcome
  • Test gets invalidated

No external devices are allowed

5. Poor Camera Setup

  • Face not fully visible
  • Camera angle incorrect
Problems
  • AI cannot verify identity properly

Your face must be clearly visible at all times

6. Bad Lighting Conditions

  • Dim or uneven lighting
Result
  • Face not clearly detected

Good lighting is mandatory—not optional

7. Internet or Technical Interruptions

  • Connection drops
  • System glitches
Impact
  • Test may be flagged for review

Stable internet is critical for a valid test

8. Suspicious Behavior Patterns

  • Unusual response timing
  • Inconsistent behavior
Why it matters
  • AI monitors patterns, not just actions

Consistency in behavior is important

9. Identity Verification Issues

  • Unclear or invalid ID
  • Mismatch with test profile
Outcome
  • Score may be rejected

Your ID must be clear and accurate

10. Not Following Instructions Properly

  • Ignoring on-screen rules
  • Rushing through setup
Result
  • Higher chance of disqualification

Instructions are part of the test—follow them carefully
