DET Practice

Freemium

DET Practice is an education tool for Duolingo English Test prep. It sits in the test-prep layer, not teaching layer. You get questions, mock tests, and AI scoring. You do not get live teachers.

The free tier gets you in the door. Paid tiers unlock more mock tests and AI feedback on speaking and writing. You pay monthly or buy single tests.

It is built for self-study. If you need hand-holding or cultural nuance in feedback, this is not your tool.

Open it if you want volume, speed, and AI scoring without a tutor. Skip it if you need human instruction or free unlimited access.

These are the people who get the most from it.

• Self-motivated learners preparing for the Duolingo English Test: You get 18,000+ questions and adaptive mock tests. You drive your own schedule.
• Students needing detailed diagnostic feedback on writing and speaking: AI breaks down vocabulary, structure, and coherence. You see exactly what to fix.
• Test-takers who want affordable AI-powered practice without live tutoring: You pay less than human tutoring costs. You still get scored practice.
• Students who only want to pay for a few mock tests: You buy single tests instead of a subscription. You stay in control of spending.
• Users who want full-length timed practice rather than isolated drills: You sit through 60-minute exams. You build stamina for test day.
• Test takers who need flexible prep fitting irregular schedules: You study in short bursts. You do not need fixed class times.
• Students who struggle with longer study sessions and need bite-sized practice: Daily short sessions add up. You do not burn out.
• Test-takers prioritizing speaking and writing feedback over reading/listening: AI scoring focuses on production skills. You get less help on input skills.

These are what you notice after using it.

• Massive question bank: Over 18,000 DET-specific questions. You never run out of material.
• Fast AI feedback: Writing and speaking scores return in about a minute. You keep momentum.
• Adaptive mock tests: Difficulty adjusts like the real test. You practice under real pressure.
• Granular scoring breakdowns: You see vocabulary, structure, and coherence separately. You know where to focus.
• Flexible buying options: Subscriptions or single tests. You pick what fits your timeline.

The path is short.

1. Sign up with Google or email for the free tier.
2. Pick practice questions or a full mock test.
3. Submit speaking or writing for AI scoring.
4. Read the breakdown and retry weak areas.
5. Upgrade to paid if you need more mock tests.

Skip it when the fit is wrong.

• No human teaching: You get AI feedback only. You miss cultural nuance and motivation.
• Limited free tier: You get a taste, then you pay. You cannot prep fully for free.
• Mock test caps: Even Pro plans limit monthly tests. You may need to buy more.
• Cluttered interface: Upselling ads appear often. You navigate around distractions.
• Self-study required: You need discipline to finish. The tool does not push you.
