What to focus your Duolingo English Test prep on

Common Duolingo English Test mistakes

The DET's format is its own thing — candidates who prep like it's IELTS get surprised by the adaptive, rapid-fire question types. People also break the at-home proctoring rules (looking away, background noise) and get results invalidated, or freeze on the timed speaking. Appmo drills the exact DET task types and timing so nothing is unfamiliar on test day.
