Teacher4.meDuolingo English Test (DET) practice online: how to prepare with a 1-to-1 tutor
Short answer: The Duolingo English Test (DET) is an online English proficiency test used by some universities and institutions. A 1-to-1 tutor can help you practise speaking and writing, time your answers and give clear feedback. A tutor cannot give you an official DET score. Always check the official Duolingo English Test website for the current format, practice materials and test-day rules.
If you are applying to a university or programme that accepts the Duolingo English Test (DET), you may be looking for a practical way to prepare. The test is taken on a computer and includes speaking and writing, not only reading and listening. Those productive skills are hard to judge on your own. A 1-to-1 online tutor cannot sit the official test for you, and cannot give you an official score, but they can listen, read your work, time you and tell you what to fix.
Before you book anything, check two official sources: the Duolingo English Test website for the current format, practice materials and test-day rules, and the admissions or language-requirements page of the school or institution you are applying to. Requirements change, and only those pages can tell you whether the DET is accepted and what they ask for.
If you are still choosing a test, start with IELTS, TOEIC, TOEFL or Eiken: which English test do you need? The DET is another option some applicants consider. Do not pick a test because a friend said it was easier. Pick the one your application actually asks for.
What a tutor can and cannot do
A tutor can help you use English more clearly under conditions that feel closer to a test: you speak out loud, you write to a time limit, and someone who is not you says whether the answer is easy to follow. They can also help you notice habits that a practice test alone will not explain, such as speaking too fast, trailing off, repeating the same words, or writing long sentences that lose the point.
A tutor cannot promise a score, a result band, or a pass. They cannot tell you, officially, how an examiner or a scoring system will mark you. They should not invent “secret” question lists or claim to have tomorrow’s test. If a teacher guarantees a result, that is a reason to choose someone else.
Treat lessons as guided practice. You still need official information and official practice from the DET website, and you still need to do work between lessons.
Start with the official format, not with guesswork
Test formats are updated from time to time. The safest habit is to read the official description of the current test before your first lesson, then send your tutor a short summary of what you saw: the skills it covers, the kind of tasks mentioned, and any rules about your computer, camera or room. If you are not sure you understood a point, say so. A good tutor will prepare practice that matches the official description, and will tell you to re-check the site if something is unclear.
Use the official practice or sample materials where they are offered. Your tutor can then review a recorded answer or a piece of writing with you and turn “I think this is weak” into a specific next step, such as “give one example before you finish” or “pause between ideas so the listener can follow.”
Do not rely on unofficial dumps of questions circulating online. They may be outdated, incomplete or simply wrong, and they will not teach you how to handle a task you have not seen before.
Speaking practice that actually helps
Speaking is often the part students worry about most, because you have to think and talk at the same time, and you cannot edit the answer afterwards. In a 1-to-1 lesson you can practise this safely.
Ask your tutor to time you. Many computer-based speaking tasks give you a short window to prepare and a short window to speak. Getting used to those limits matters more than producing a perfect monologue with unlimited time. If you run out of things to say, practise a simple structure: answer the question, add one reason, add one short example, then stop. If you speak past the point and start repeating yourself, practise landing a clear closing sentence.
Ask your tutor to record the answer, or record it yourself and listen together. It is difficult to hear your own pace, fillers (“um”, “you know”) and unfinished sentences in the moment. A second listen makes them obvious.
Work on intelligibility, not on copying a particular accent. Clear sounds, steady pace and complete sentences help a listener more than a forced accent. If a word is hard to hear, your tutor should stop you and practise that word in a sentence, not only in isolation. For more on this, see English pronunciation practice online.
Also practise following a prompt exactly. In a test, going off-topic or answering a slightly different question wastes time. Your tutor can read a prompt, let you answer, then ask: “Did you actually answer this, or did you talk about something nearby?”
If you freeze when you do not know a word, practise recovery language you already know: “The thing you use to…”, “I am not sure of the exact word, but I mean…”. This is ordinary communication, and it keeps you talking instead of stopping.
Writing practice that a tutor can mark properly
Writing is the other skill that benefits from a real reader. A 1-to-1 tutor can tell you whether your idea is clear in the first sentence, whether the paragraph stays on one point, and whether the ending answers the task.
Bring a timed writing to the lesson, or write it live. Then ask for feedback in a useful order: first, did you complete the task? Second, is the organisation easy to follow? Third, are there grammar or word-choice problems that make the meaning hard to read? If a tutor only corrects every article and preposition and never talks about structure, ask them to start with the bigger issues.
Practise writing that is simple and complete rather than long and impressive. A short paragraph with clear sentences is easier to follow than a dense block of clauses. If you often write run-on sentences, your tutor can help you split them. If your writing jumps between ideas, they can help you use a plain plan: position or main point, reason, example, short conclusion.
Between lessons, rewrite one paragraph using the feedback, and bring both versions next time. That is how the advice turns into a habit. For a broader look at writing with a tutor, see English writing practice online.
Reading and listening: use lessons for the hard parts
You can practise a lot of reading and listening on your own with official or other level-appropriate materials. Lessons are more valuable when you use them to inspect the mistakes you keep making. For example, if you miss the main idea of a passage, your tutor can show you how they find it. If you hear a conversation but cannot catch the speaker’s purpose, you can replay a short extract and talk about the clues.
If listening is your weak point, say so early. You may want some lesson time on dictation of short sentences, checking key words, or explaining what you heard in your own words. See also English listening practice online.
Do not spend paid lesson time only clicking through practice questions in silence. Do that between lessons. In the lesson, talk about why an answer worked or did not.
A simple way to plan the weeks before the test
You do not need a complicated system. You need a regular time, a clear focus and a way to see whether you are improving.
First, set a realistic test date after you have read the official requirements and booked the official test only when you are ready to follow its rules. Then tell your tutor that date.
Second, agree what you will practise in lessons and what you will do alone. A common split is: official practice and review at home; speaking and writing feedback in the lesson; a short recap of new phrases at the end.
Third, keep a simple log: date, what you practised, one thing that went better, one thing to repeat. This helps you and your tutor decide the next lesson instead of starting from zero each time. For a fuller approach, see how to track your English progress with an online tutor.
Fourth, do at least one practice run in conditions that are closer to the real test: same kind of room, same kind of device, no notes, full attention. Then review it with your tutor. The goal is not to frighten yourself. It is to discover problems while you still have time to fix them, such as a microphone habit, a rushed start, or running out of time on writing.
If your test is still far away and your English is at an early stage, it may be better to build general speaking and writing first, then move into test-style practice. A tutor can help you judge that in a trial lesson. See questions to ask a tutor in a trial lesson and, if you are starting out, learning English online as a complete beginner.
What to tell a tutor in your first message
A short, specific message gets a more useful reply than “I want to study DET.” Include:
- That you are preparing for the Duolingo English Test, and the month or date you are aiming for, if you have one.
- Why you are taking it (for example, a university application), without sending private application details you do not need to share.
- Your current level in your own words, and which skill worries you most: speaking, writing, reading or listening.
- Whether you have already tried official practice, and what felt difficult.
- The days and times you can do lessons, including your time zone.
Then ask how they would structure practice for this test, and whether they have helped students prepare for computer-based English tests before. You are not asking for a promised score. You are asking whether their style fits the work you need to do.

Frequently asked questions
What is the Duolingo English Test?
The Duolingo English Test is an English proficiency test that you take on a computer. Some universities and other institutions accept it as evidence of English level. Each school sets its own requirements, so check the official page of the place you are applying to, and read the current information on englishtest.duolingo.com.
Can a tutor give me a Duolingo English Test score?
No. A practice session with a tutor is not an official Duolingo English Test and cannot give you an official score. A tutor can listen, read your writing and tell you what is clear, what is confusing and what to practise next. Only the official test can produce a score for an application.
What should I practise with a tutor before the DET?
Focus on the skills you cannot easily check alone: speaking clearly under time pressure, answering follow-up questions, and writing that is organised and easy to read. Also practise following instructions carefully and staying calm if a task feels unfamiliar. Use official practice materials from the DET website alongside your lessons.
How is the DET different from IELTS or TOEFL?
They are different tests, with different formats and different lists of institutions that accept them. The DET is taken on a computer and includes speaking and writing as well as reading and listening. Which test you need depends on the school or organisation you are applying to, not on which one is “easier”. See which English test do you need? and always confirm on the official pages.
How do I find a DET tutor on Teacher4.me?
Open Find a teacher and search for Duolingo, DET or exam preparation, then read each teacher's subjects, reviews and prices. In your first message, say you are preparing for the Duolingo English Test and when you plan to take it. You can message a teacher without an account and book and pay the teacher directly.
