Its central promise is exam-style practice combined with automated feedback: learners work through sections covering speaking, writing, listening, and reading, then receive AI-generated scoring and suggestions aimed at pushing them toward a higher band. The content side is substantial. The platform advertises more than 15,000 practice questions organised by question type and difficulty, so you can drill specific task formats rather than only taking full mock tests. Around that core sit study tools: CEFR-based vocabulary assessment, personal word lists clustered from your practice data, performance statistics, and score analysis that flags weak areas. There is also a community element, with a study group of active users for shared preparation. The pricing model is generous for a test-prep resource, offering free practice questions and basic features, with premium AI scoring and deeper analytics available for full preparation. One thing to note: OETStudy states plainly that it is not endorsed by or affiliated with Duolingo, so it should be treated as third-party preparation support rather than an official source of DET scores. **Pricing & Plans:** OETStudy offers free practice questions and basic features, with premium features covering comprehensive preparation such as AI scoring and detailed analytics. No credit card is required to start. - **15,000+ practice questions:** A large bank of DET-style items spanning speaking, writing, listening, and reading, graded by difficulty so you can practise at the level you need. - **AI speaking and writing scoring:** Speaking and writing submissions are scored automatically, evaluating pronunciation, fluency, grammar, and content structure with suggestions for improvement. - **CEFR vocabulary tools:** Check your vocabulary level against CEFR bands and build word lists clustered around the question types you practise most. - **Progress analytics:** Practice statistics and score analysis highlight weak areas and show how your performance changes over time. - **Targeted question drills:** Focus practice on the specific DET task types where you need the most improvement rather than working through everything equally. **Strengths:** Large, DET-aligned question bank across all four sections; AI scoring provides instant speaking and writing feedback; CEFR and vocabulary tools support longer-term language growth; Free tier lets you practise before paying for premium features **Limitations:** Some content and features are JS-dependent and may not render on older browsers; Premium scoring and analytics sit behind the free practice tier; AI scoring is a practice aid and not the official DET result [Profile (Markdown)](https://openaitools.app/tool/oetstudy-com.md) ## Prep Edu Prep Edu is built around the idea that most test takers fail to raise their band scores not because they lack information, but because they get too little active practice and almost no feedback. The platform pairs a conventional course library — IELTS, TOEIC, HSK and a PrepTalk English conversation track — with AI environments where learners actually speak and write and then immediately see how they performed. The AI Virtual Speaking Room and Virtual Writing Room are the centre of that loop, scoring responses and commenting not only on grammar and pronunciation but on ideas, logic and vocabulary choice. A second layer is guidance. Teacher Bee AI acts as a 24/7 learning companion, helping learners move through lessons and unblock difficult tasks between scheduled study sessions. Prep also bundles entry tests, mock exams, progress tracking and study-roadmap tools so learners can see where they stand relative to their target score. The product is aimed squarely at exam-oriented learners who study from home — students and working professionals preparing for IELTS, TOEIC or HSK in Vietnam and across Southeast Asia, where the platform is actively expanding through education-technology events and institutional partnerships. Teacher and institution support is also part of the offering, with teacher-facing tools marketed alongside the learner experience. **Pricing & Plans:** Paid, course-based. Prep Edu sells structured IELTS, TOEIC, HSK and PrepTalk English packages rather than a single flat subscription, and the exact fee depends on which program and length you choose. Current prices are shown on the course pages after you select a track, so treat any figure you see in older reviews as potentially out of date. - **Prep AI Virtual Speaking Room:** Rehearse exam-style speaking tasks with AI scoring and multi-layer feedback covering grammar, pronunciation, fluency, vocabulary and how well your ideas are organised. - **Prep AI Virtual Writing Room:** Submit written answers and receive automated scoring with suggestions on structure, vocabulary range and accuracy to raise your band score. - **Teacher Bee AI companion:** A companion that answers questions, walks through difficult tasks and keeps learners motivated between lessons. - **Structured courses and mock tests:** Structured IELTS, TOEIC and HSK programmes, a PrepTalk English speaking course, entry tests and mock exams that mirror the real format. - **Personalised roadmap and mobile app:** A personalised learning path, daily progress tracking, score reporting and the Prep app for studying on the go. **Strengths:** Combines real course content with AI speaking and writing practice in one place; Feedback covers ideas, logic and vocabulary, not just surface grammar correction; Large active learner base with a well-known presence in the Vietnamese exam-prep market; Works fully online and via app, suited to studying at home on a flexible schedule **Limitations:** Course pricing varies by program and is not fully transparent until you talk to sales or log in; Heaviest focus is on IELTS/TOEIC/HSK, so it is not ideal for learners targeting other exams or general fluency only; Effectiveness still depends on learner discipline; AI feedback on ideas and logic is helpful but not a substitute for expert human tutoring; Some testimonials and score banners are marketing-heavy, so results should be judged against your own baseline and study time [Profile (Markdown)](https://openaitools.app/tool/prep-edu.md) ## Frequently Asked Questions ### How do OETStudy and Prep Edu compare in monthly traffic?
