How to prepare for the Duolingo English Test: 2-week and 4-week study plans
Most students preparing for the Duolingo English Test (DET) need two to four weeks, not months. The test measures general English, so you cannot learn a new level in a fortnight, but you can stop losing points to the format: unfamiliar timers, blank answers, short speaking turns, typing errors. Those losses are often worth 10–20 points. This guide gives a diagnostic, a 2-week plan for students close to their target, and a 4-week plan for those further away.
The format details follow Duolingo’s 2026 Question Guide; the plans themselves are our recommendations.
Step 1: find your starting point
Before you plan anything, take two timed tests in the same week:
- Duolingo’s free official Practice Test. It uses the same question types, adapts like the real test and gives an estimated score range. You can take it as many times as you like, and the pool is large enough that questions rarely repeat.
- A full Nomto practice test. It estimates your overall score and all four subscores on 10–160 and reviews every speaking and writing answer with corrections, so you see why you lost points.
Write down three numbers: your overall estimate, your target (the highest minimum among your programs), and your lowest subscore. Then pick a plan:
| Gap to target | Plan |
|---|---|
| 0–10 points | 1 week of format practice, then book |
| 10–20 points | the 2-week plan |
| 20–35 points | the 4-week plan |
| more than 35 points | build general English for a few months first, then the 4-week plan |
What to practice for each subscore
The overall score is the average of four subscores, so the weakest one matters most. Raising it by 20 points lifts the overall score by about 5.
- Reading: Read and Select, Fill in the Blanks, Read and Complete, Interactive Reading. Drill vocabulary recognition, word endings and spelling.
- Listening: Listen and Type and Interactive Listening. Drill dictation and choosing replies that fit tone and context.
- Writing: the three photo descriptions, Interactive Writing, the Writing Sample and the conversation summaries. Drill fast, complete, linked sentences.
- Speaking: the photo, Read, Then Speak, Interactive Speaking and the Speaking Sample. Drill speaking for the full time without long pauses.
The 2-week plan (45–60 minutes a day)
Week 1: learn every task and fix the obvious losses
| Day | Focus | What to do |
|---|---|---|
| 1 | Diagnostic | both practice tests; list your three weakest question types |
| 2 | Read and Select + Fill in the Blanks | 60 words at 5 seconds each; 15 sentences at 20 seconds; note misspellings |
| 3 | Read and Complete | 4 paragraphs at 3 minutes; never leave a gap |
| 4 | Listen and Type | 15 sentences; check plural -s, -ed, articles, punctuation |
| 5 | Photo tasks | 3 written photos (1 minute each) + 2 spoken photos (90 seconds); use the structure from the guides |
| 6 | Interactive Reading + Listening | 1 set of each under time; review every wrong answer |
| 7 | Interactive Writing + Writing Sample | 1 of each; rewrite one answer using the feedback |
Week 2: speed, speaking and a final mock
| Day | Focus | What to do |
|---|---|---|
| 8 | Interactive Speaking | 2 sets of 6–8 questions at 35 seconds; record and listen back |
| 9 | Your weakest reading task | 30 minutes of drills, then 1 Interactive Reading set |
| 10 | Read, Then Speak + Speaking Sample | 2 of each; speak until the time ends |
| 11 | Mixed | 1 of every task type, timed, no pauses between |
| 12 | Full mock | Nomto practice test; compare subscores with Day 1 |
| 13 | Fix | redo the two task types that lost the most points |
| 14 | Rest and check | official Practice Test once; prepare your room and ID |
The 4-week plan (60–90 minutes a day)
Weeks 1–2 build the base, weeks 3–4 follow the 2-week plan above with more volume.
Week 1: vocabulary and spelling. Every day: 50 Read and Select items, 10 Fill in the Blanks, one Read and Complete paragraph, and 10 new words from your mistakes. Keep a spelling list of every word you mistype and read it before each session. Read one short article a day from a news or popular-science site and underline words you could not spell from memory.
Week 2: listening and typing. Every day: 10 Listen and Type sentences, one Interactive Listening set, and 10 minutes of dictation from any English podcast or lecture (play a sentence, type it, check). If you type slowly, add 10 minutes of typing practice: speed matters in a test with one-minute timers.
Week 3: writing and speaking. Alternate days. Writing days: three photos, one Interactive Writing, one Writing Sample. Speaking days: one photo, one Read, Then Speak, one Interactive Speaking set, one Speaking Sample. After each, read the feedback and redo one answer with the corrections. Use the frameworks and model answers in DET writing tasks and DET speaking tasks.
Week 4: the 2-week plan’s week 2, plus a full mock on Day 22 and Day 26.
Habits that move scores fastest
- Always answer. In Read and Complete, a blank scores the same as a wrong word, and in Read and Select a timeout is wrong. A guess can only help.
- Use the whole time in speaking. The DET scores content and fluency. A 40-second answer to a 90-second photo leaves points unused.
- Answer the question, then add one detail. In Interactive Speaking you have 35 seconds: a direct answer, a reason, an example.
- Proofread in the last 10 seconds. Writing scores include grammar and spelling. Capital letters, full stops and -s endings are cheap points.
- Read the scenario once, then use it. In Interactive Listening, the information from Listen and Complete helps you choose replies and write the summary.
- Practice on the computer you will use. The keyboard, microphone and camera should be familiar by test day.
Common mistakes in preparation
- Only taking practice tests. A test tells you your level; it does not raise it. Spend most time on targeted drills and use full tests weekly.
- Memorizing long templates. Duolingo’s scoring looks for answers that are off topic or repetitive and gives them very low scores. Learn short structures, not paragraphs.
- Studying removed tasks. Read Aloud and Listen, Then Speak were removed in July 2025. Check that your materials show Interactive Speaking; the 2026 format guide lists every current task.
- Booking too early. If your last two mocks are below target, another week is cheaper than another test.
The week before the test
- Read the setup rules in fee, registration and how to take it at home: room scan, ear scan, phone camera, ID.
- Do one timed mock at the same time of day as your test.
- Sleep normally the night before. The test is one hour of quick decisions; a tired brain loses more on Read and Select than on any essay.
Practice in the Nomto room
Each question type has its own drill in the Nomto DET room, and full practice tests estimate your score on 10–160 with four subscores. A free account includes 10 reading and listening items, 3 spoken and 1 written answer reviewed by AI and a one-section mock, with explanations in English, Spanish, Portuguese, Indonesian or Russian. Our scores are estimates, so use Duolingo’s official Practice Test for a final check.
Common questions
How long does it take to prepare for the Duolingo English Test? Two to four weeks for most students already near their target; longer if you need to raise your general level.
Is the official practice test enough? It is the best way to check your estimated range, but it gives a score, not feedback. Pair it with practice that reviews your answers.
Can I prepare for the DET without a teacher? Yes. The tasks are short and predictable; what you need is timed practice and honest feedback on speaking and writing.
What should I do on the last day? One light review, a check of your room and documents, and rest.
