DETPractice vs TOEFLMock

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.

TOEFLMock provides TOEFL iBT practice aligned with the January 2026 format, with full mock exams and practice for individual sections. Its library is described as 20 full-length exams and 80 section tests. Reading and Listening tests use two-module routing, with performance in the first module determining the next one. Scores use a 1–6 band scale, map to CEFR levels and can also be converted to the legacy 0–120 scale. Speaking and Writing responses receive rubric-based scores, explanations tied to rubric criteria and three suggested improvements. The maker says feedback typically arrives within 30 minutes, though waits can be longer during exam peak weeks. A personal dashboard tracks section weaknesses, band trends, expert feedback and mistakes to review. Paid plans add a 45-lesson course, 1,000 practice questions across 10 task types and 1,500 speaking questions across three tracks. Institute plans include student monitoring, assigned tests and cohort analytics. Practice runs in modern browsers on phones, tablets, Chromebooks, laptops and desktops without app installation. The service is independent and its scores are practice estimates, not official ETS scores.
