Interactive Writing is the Duolingo English Test’s longest written task and it comes in two parts: 5 minutes on an opening prompt, then 3 minutes on a follow-up question generated from what you just wrote. The Writing Sample is a separate task – one prompt, about 5 minutes – and it is both graded and sent to the universities you choose, so they read it themselves. Together these two tasks carry most of your Writing, Literacy and Production subscores, which means they carry most of the gap between a 105 and a 125.
The winning approach is not better English. It is a fixed structure you can deploy in fifteen seconds, enough words to show range (120+ in Part 1, 60+ in Part 2), and sixty seconds of proofreading you do not skip. Below: templates for all three prompt types, a minute-by-minute timing plan, a full model answer, and the errors Arabic speakers repeat. Still mapping the test? Start with the DET question types and how scoring works.

What each task actually is
Interactive Writing. A written prompt appears for about 30 seconds before the timer starts – you can click Continue to begin early, but do not; use those seconds to plan. You then have 5 minutes for Part 1. When time is up the test gives you a follow-up question built from your own answer and 3 minutes to respond. Part 1 stays visible while you write Part 2, but you cannot edit it.
Writing Sample. One prompt, about five minutes, no follow-up. It is graded into Writing, Literacy and Production and the institutions receiving your results get your actual text – so it is read twice, once by the scoring system and once by a human admissions officer.
| Interactive Writing | Writing Sample | |
|---|---|---|
| Parts | 2 (5 min + 3 min) | 1 (≈5 min) |
| Follow-up | Yes, generated from your answer | No |
| Editing | Part 1 locked once Part 2 starts | Editable until time ends |
| Sent to universities | No | Yes |
| Target words | 120+ / 60+ | 120+ (130+ if targeting 120 and above) |
The three prompt types – and one template each
Every DET written prompt is one of three kinds. Learn the trigger words and you will know your structure before you finish reading the question.
Type 1 – Recount. Triggers: Describe a time when…, Tell us about an experience…, Write about a memory…
- Sentence 1: name the event and when it happened.
- Sentences 2-3: the situation – where, who, why it mattered.
- Sentences 4-5: what happened, in order.
- Sentence 6: the outcome.
- Sentence 7: what you learned or how you feel about it now.
Type 2 – Describe. Triggers: Describe a place/person/object…, What is…like in your country?, Explain how…
- Sentence 1: name the thing and give a one-line overview.
- Sentences 2-3: two concrete features, with detail.
- Sentences 4-5: one example or a typical scene.
- Sentence 6: why it matters, or how it compares to an alternative.
- Sentence 7: a closing evaluation.
Type 3 – Argue. Triggers: Do you agree…, Some people think… What is your opinion?, Which is better…
- Sentence 1: state your position directly. No throat-clearing.
- Sentences 2-3: first reason + evidence or example.
- Sentences 4-5: second reason + example.
- Sentence 6: acknowledge the other side in one clause (Although some people argue that…).
- Sentence 7: restate the position in different words.
All three are seven sentences – deliberately, because seven sentences at 17-18 words each is about 125 words, exactly the target.
Timing: the minute-by-minute plan
| Task | Time | What you do |
|---|---|---|
| Interactive Writing Part 1 | 0:00-0:30 (preview) | Read the prompt twice. Decide the type. Decide your position or your event. |
| 0:00-0:45 (timer) | Write sentences 1-2. Do not plan further – the structure is already decided. | |
| 0:45-4:00 | Write sentences 3-7 continuously. Do not stop to correct. | |
| 4:00-5:00 | Proofread: articles, verb endings, plurals, spelling, one missing word per paragraph. | |
| Interactive Writing Part 2 | 0:00-0:30 | Read the follow-up. Pick one specific angle – do not repeat Part 1. |
| 0:30-2:30 | Write 3-4 sentences: direct answer, one reason, one example, one close. | |
| 2:30-3:00 | Proofread. | |
| Writing Sample | 0:00-0:30 | Identify the type, decide the content. |
| 0:30-4:00 | Seven sentences, continuous writing. | |
| 4:00-5:00 | Proofread and add one more sentence if you are under 120 words. |
The most common timing failure is spending the first minute thinking; the templates exist so thinking takes fifteen seconds. The second is proofreading the whole last minute without adding a sentence when the answer is short – check your word count first, fix errors second.
A full model answer (Argue type, 137 words)
Prompt: “Some people believe that students learn better in online classes than in traditional classrooms. Do you agree? Explain your opinion.”
Model answer:
“I believe online classes can be more effective than traditional ones, but only for motivated students. The first reason is flexibility. A student who works during the day can attend a later session or watch the recording afterwards, which is simply impossible in a physical classroom. In my own case, I prepared for an English exam through flexible online classes while I was still working full time, and I would have had to postpone a whole year otherwise. The second reason is the quality of the recordings. Being able to replay a difficult explanation three times is worth more than hearing it perfectly once. Although some people argue that online students lose the discipline of a classroom, I think a clear schedule solves that problem. For a motivated learner, online study is the stronger option.”
Why this scores: it takes a position in sentence one and qualifies it (“but only for motivated students”), which shows control; it uses two developed reasons with a concrete example; it concedes the other side with Although; it varies sentence length from 9 to 33 words; and its articles are accurate throughout. Nothing in it requires rare vocabulary.
Likely Part 2 follow-up: “You mentioned that motivation matters. How can a student stay motivated in an online course?”
Model Part 2 (68 words): “The most practical method is fixing the study time in advance and treating it like a real appointment. I fix the same study hour every day and I never move it, which removes the daily decision of whether to study. Studying with one classmate also helps, because you feel responsible to someone else. Motivation fades quickly, so the schedule has to carry you when the enthusiasm does not.”
Mistakes that cost Arabic speakers the most here
1. Missing or extra articles. “I am student”, “The education is important”. Arabic has no indefinite article and uses the definite one for general nouns. On a 130-word answer this error can appear eight times. Fix it in the proofreading minute: underline every singular countable noun mentally and check it has a, an or the.
2. Run-on sentences joined with ‘and’. “Online learning is good and it saves time and also it is easier and students can study anywhere.” Good Arabic style, weak English style, and it caps your Literacy score because the grader sees one structure repeated. Break it into three sentences with different shapes.
3. Writing too little. Under 100 words makes a high Writing subscore almost impossible regardless of accuracy. Count your sentences: if you have fewer than six, add an example.
4. Repeating Part 1 in Part 2. The follow-up asks for something new. If you restate your original argument, Part 2 adds nothing. Give a specific method, a specific example or a specific consequence.
5. Spelling traps. necessary, accommodation, beginning, environment, government, receive, believe, different, interesting. Type each one five times in a text box before your test.
6. Memorised openings. “In this modern era of globalisation, technology has become an integral part of our daily lives.” Graders have read it ten thousand times and it answers no prompt. Start with your actual answer. More in DET common mistakes and our Arabic-speaker mistakes guide.
Linking phrases worth memorising (and the ones to avoid)
| Function | Use these | Avoid |
|---|---|---|
| Adding a reason | The main reason is…, This matters because… | Firstly, Secondly, Thirdly (in a 7-sentence answer it sounds mechanical) |
| Giving an example | For example, In my own case, To give one example | Such as at the start of a sentence |
| Contrasting | Although…, However, On the other hand | In the other hand, In contrary |
| Consequence | As a result, which means that… | So (too informal, over-used) |
| Concluding | Overall, For these reasons, On balance | In a nutshell, Last but not least |
Ten to twelve phrases are enough. Six used accurately beat fifteen with two errors, because accuracy and range are measured together.
A four-day practice routine for these two tasks
- Day 1: write three Writing Samples, one of each prompt type, strictly timed at five minutes. Do not edit afterwards. Count the words. Mark every error by category.
- Day 2: four complete Interactive Writing sets (Part 1 + Part 2). Force Part 2 above 60 words every time.
- Day 3: rewrite your three day-1 answers with the errors fixed and one extra sentence added. Compare the two versions side by side – this is where the learning happens.
- Day 4: two more full sets under mock conditions, plus fifteen minutes of typing practice and five minutes on your personal spelling list.
If you want your answers corrected rather than self-marked, that is the core of what we do: every student on our courses gets personal Speaking and Writing correction on their own answers. The standard course runs live on Zoom in Arabic and English at a steady pace; the intensive course covers the same content in fewer days with more hours a day when your test is close; and the private course is one-to-one, built around you.

Frequently asked questions
How long is DET Interactive Writing?
Two parts: 5 minutes on the first prompt and 3 minutes on a follow-up question generated from your own answer. The prompt is shown for about 30 seconds before the Part 1 timer starts.
How many words should I write?
Aim for 120 or more in Part 1 and the Writing Sample, and at least 60 in Part 2. Below 100 words it is very hard to reach a high Writing subscore however accurate your English is.
Can I edit Part 1 after moving to Part 2?
No. Part 1 stays visible so you can refer to it, but it is locked. That is why the last minute of Part 1 is for proofreading, not for writing more.
Is the Writing Sample really sent to universities?
Yes. It is graded into your Writing, Literacy and Production subscores and the institutions receiving your results also read the text itself, so write it as something a human will judge.
Should I use a memorised template?
Use a memorised structure, not memorised sentences. A seven-sentence skeleton for each of the three prompt types is enough; memorised opening paragraphs are recognisable and score poorly.
What are the three prompt types?
Recount (describe an experience), Describe (explain a place, person, object or process) and Argue (give and defend an opinion). Almost every DET writing prompt is one of these.
Does typing speed matter?
A lot. At 25 words per minute you cannot physically produce 120 good words in five minutes with time left to proofread. Train to 40+ wpm at 90% accuracy.
What is the fastest way to improve my Writing subscore?
Three things in order: write longer answers, vary your sentence structures instead of chaining clauses with ‘and’, and keep a strict final minute for proofreading articles, plurals and spelling.
