DETPractice vs IELTS Online Tests

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, plus 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, while an AI tutor can answer DET questions, check grammar, translate, rewrite text, and create practice content. The free tier includes all question types, more than 300 practice questions, basic explanations, and limited access to some features. Basic costs $9.90 a month, Plus costs $19.90 a month, and Pro costs $39.90 a month; paid tiers list varying mock-test and AI-correction allowances. Mock-test access expires after 90 days. The same account and supported learning history can be used in a browser and the mobile apps. DETPractice describes itself as a Platinum Partner for test preparation, while noting that its practice questions and mock tests do not replace the official Duolingo English Test.
