It offers a large bank of exam-style questions, AI-powered scoring for speaking and writing tasks, CEFR vocabulary checks, and progress analytics to help learners target a higher score. **價格與方案:** 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. **優勢:** 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 **限制:** 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/tw/tool/oetstudy-com.md) ## Prep Edu Prep Edu is an online language-learning and exam-preparation platform combining structured IELTS, TOEIC and HSK courses with AI-powered practice. Its Prep AI Virtual Speaking Room and Virtual Writing Room simulate real exam conditions and return feedback on grammar, pronunciation, vocabulary, ideas and logic, while the Teacher Bee AI companion offers round-the-clock guidance. Learners get a personalised roadmap, mock tests, progress tracking and mobile access for studying at home. **價格與方案:** 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. **優勢:** 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 **限制:** 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/tw/tool/prep-edu.md) ## 常見問題 ### OETStudy 與 Prep Edu 的每月流量相比如何？ OETStudy 每月有 4,738 次造訪，而 Prep Edu 有 1,414,975。流量估算反映受眾規模，並非產品品質。 ### 兩者的成長率相比如何？ OETStudy 的月增率為 +264.2%；Prep Edu 為 -19.8%。 ### 價格相比如何？ OETStudy：免費。OETStudy offers free practice questions and basic features, with premium features covering comprehensive preparation such as AI scoring and detailed analytics.
