- TestReady (Android): $9.99 per mock, DET-specific practice with the real 10-160 scoring. - Duolingo English Test official practice: free, the closest thing to the real interface. - DET practice apps (Play Store): question banks for the adaptive format, free with ads. - Yocket (Android): community tips from students who scored 120+. Sources: IELTS The DET is adaptive: the test gets harder as you answer well. Practice on apps that adapt too, or the real test will feel like an ambush. Aim 120+ for 6.5-equivalent programs; 105 buys you the 6.0 tier.
Duolingo English Test prep apps help most when they drill the question types a 105 score demands.
