DETPractice vs Official PTE Academic AI Practice

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.

Official PTE Academic AI Practice is a web-based preparation product for people studying for the PTE Academic exam. It provides practice questions, mock tests, AI scoring and feedback, and a dashboard showing scores by skill and progress across sessions. Questions written by the PTE test development team cover all four skills. Free access includes two diagnostic tests, sample Reading and Listening questions, and sample AI scoring and feedback. Paid access adds 15 full-length mock tests, 20 sectional tests, and more than 1,000 official practice questions. AI scoring estimates results and provides trait-level insights aligned with official PTE scoring traits; an AI Tutor can discuss performance and guide what to practice next. Questions can be repeated during access, but each mock and sectional test allows only one attempt. Paid plans are one-time payments: 29.99 USD for 7 days, 59.99 USD for 1 month, or 89.99 USD for 3 months. Pearson says access ending does not trigger an automatic charge.
