DETPractice
What it is
DETPractice is a preparation platform for the Duolingo English Test, available on the web, iOS, and Android. It offers more than 18,000 practice questions, with content described as updated every day, as well as courses, lessons, guides, and other learning materials. Adaptive full-length mock tests provide estimated scores in one to five minutes. AI tools score and correct speaking and writing responses, and an AI tutor can answer DET questions, check grammar, translate, rewrite text, and generate practice content. The free tier includes all question types, more than 300 practice questions, basic explanations, and limited access to some features. Paid plans list different monthly allowances for mock tests and AI corrections. Mock-test access expires after 90 days. The same account and supported learning history can be used in a browser or the mobile apps. DETPractice describes itself as a Platinum Partner for Duolingo English Test preparation, but its practice questions and mock tests do not replace the official test.
