OETStudy

OETStudy is an online preparation platform specifically designed for the Duolingo English Test (DET). It focuses on helping test takers improve their scores through a structured, AI-assisted practice environment. The platform provides a large question bank containing over 15,000 practice items that cover all question types appearing in the actual DET, including speaking, writing, listening, reading, vocabulary, and grammar. Each question is graded by difficulty levels, allowing users to start with basic exercises and gradually progress to more challenging ones. The core functionality relies on artificial intelligence to evaluate spoken and written responses. Users can record their speaking answers and receive instant feedback on pronunciation, fluency, coherence, and vocabulary usage. Similarly, written responses are analyzed for grammar accuracy, sentence structure, and topic relevance. This immediate scoring mechanism helps learners identify specific areas that need improvement without waiting for human evaluation. Beyond practice questions, OETStudy offers personalized study plans based on individual performance data. After completing a set of exercises, the platform analyzes the user’s weak points and suggests targeted practice sessions. For example, if a user consistently makes mistakes in listening comprehension, the system will recommend more listening drills with similar difficulty. This adaptive approach ensures that study time is used efficiently. The platform also includes simulated full-length DET exams that replicate the actual test environment. Users can take timed mock tests to build familiarity with the test structure and pacing. After each mock test, a detailed report is generated, breaking down scores by skill area and showing comparative performance t
