## DET Practice

DET Practice is a preparation platform built specifically for the Duolingo English Test, positioning itself as a Platinum Partner of the exam. Its centrepiece is a question bank of more than 18,000 items that is updated continuously, paired with model answers and explanations so learners can see not only what the correct response is but why a high-scoring answer works. The platform reports over 400,000 users and 40,000 mock tests taken.

The mock exam experience is designed to mirror the real test: adaptive difficulty, the same task types, and AI scoring that returns a detailed evaluation report within a few minutes. Alongside the mock tests sit dedicated speaking and writing correction services — covering tasks such as Write about the Photo, Interactive Writing, Writing Sample, Read Aloud, Listen then Speak and Speak about the Photo — where learners receive AI scoring combined with teacher guidance.

For learners who want structure, there are courses covering the DET speaking and writing sections developed by ESL instructors, plus a broader AI tutor that corrects grammar, translates across languages and helps generate or polish writing. DET Practice also bundles exam-day perks: members can claim a coupon for a discount on the actual DET fee, and results within 24 hours through a sponsor invite link. The site holds a 4.8/5 rating across more than 1,850 reviews, with feedback frequently highlighting question quality and the depth of mock exam reports.

**Pricing & Plans:** DET Practice is freemium: you can start free with Google or email and try core practice and mock tests. Paid membership tiers unlock correction services, courses and unlimited access, and the site notes that cancellations are possible at any time.

## OETStudy

OETStudy is an independent study platform built around the Duolingo English Test, an online proficiency exam many universities accept. 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
