DET Practice

DET Practice is an online platform for preparing for the Duolingo English Test (DET), focused on matching the real exam format and providing consistent scoring feedback.

Practice that matches the DET format

The platform offers a large question bank designed around the structure and task types used in the official test. You can train specific skills in short sessions or take full-length mock exams that follow the same order and timing as the real DET.

AI scoring and targeted feedback

Responses are evaluated with AI scoring aligned to Duolingo English Test criteria. You receive a score, see weak areas, and track improvement across attempts. For more challenging tasks, you can use correction and detailed breakdowns to understand how to improve writing and speaking.

Courses and progress analytics

Built-in courses and topic-based practice help you prepare toward a target score. Session statistics highlight which task types need work and help you allocate time across reading, listening, writing, and speaking.
