Duolingo English Test extended writing task practice

B2Reading & Writing40 questionsUpdated

The extended writing task on the Duolingo English Test gives you a prompt and several minutes to write a developed answer. This is the one task where planning pays for itself, because a clear structure lets you write quickly without stopping to think about what comes next.

What this task tests

  • Whether you answer every part of the prompt, not just the part you find easy.
  • Development: whether each point is supported with a reason or an example.
  • Range of linking language, from simple ‘because’ to ‘as a result’ and ‘on the whole’.
  • Grammatical accuracy over a longer stretch of writing than the photo task.
  • Paragraphing and shape: an answer that has a beginning, a middle and an end.
  • Whether you can plan quickly rather than writing whatever comes next.
  • Sentence variety: a mix of simple and complex sentences rather than twenty of the same shape.
  • Word choice under pressure — precise verbs rather than ‘get’, ‘make’ and ‘do’ everywhere.
  • Whether you can finish, including a conclusion, inside the time.
  • Self-correction: whether the last thirty seconds are used or wasted.

How to do it

  1. Step 1:

    Spend the first forty seconds planning

    Read the prompt twice and note two reasons and one example for each. Writing without a plan means stopping mid-paragraph to think, and those pauses cost more than the plan did.

  2. Step 2:

    State your position in the first sentence

    Do not build up to it. ‘I think employers should allow staff to work from home two days a week’ tells the reader everything and gives you a thesis your paragraphs can support.

  3. Step 3:

    Give each paragraph one idea and one example

    Point, reason, example. Three sentences per paragraph is enough. An example from your own life is quicker to write and more convincing than an invented statistic.

  4. Step 4:

    Answer both halves of a two-part prompt

    If the prompt asks what you think and why, or asks for advantages and drawbacks, write a paragraph on each. Missing half the prompt caps the mark however well the other half is written.

  5. Step 5:

    Save the last thirty seconds for checking

    Scan for three things only: third-person -s, plural -s, and articles. Those three fixes catch most of the errors you will actually have made, and the scan is fast enough to finish.

  6. Step 6:

    Vary sentence length on purpose

    Write one long sentence with a subordinate clause, then a short one. ‘Although the fare rose, journeys increased. The reason is simple.’ That rhythm shows range without risking a sentence you cannot control.

  7. Step 7:

    Use a conclusion of one sentence

    ‘On the whole, the advantages outweigh the drawbacks for most families.’ One sentence is enough. A long conclusion repeats the essay and eats the checking time.

  8. Step 8:

    Reach for precise verbs

    Replace ‘get better’ with ‘improve’, ‘make a decision’ with ‘decide’, ‘do research’ with ‘investigate’. One or two of these per paragraph raise the register without any risk of error.

  9. Step 9:

    Write your plan as three words, not three sentences

    ‘cost / time / example: commute’ is a plan. Writing full sentences in the plan means writing the answer twice, and the clock does not care that the first version was in note form.

  10. Step 10:

    Never start a paragraph you cannot finish

    With ninety seconds left, add a sentence to an existing paragraph and then conclude. An abandoned third paragraph reads as poor organisation, not as ambition.

Mistakes that cost marks

  • Not thisWriting four hundred words with no paragraph breaks.

    ThisThree or four short paragraphs with one idea in each.

    Length alone does not raise a writing score. An unstructured block hides your organisation, which is part of what is being judged.

  • Not thisIn my opinion, I think that personally I believe that remote work is good.

    ThisIn my opinion, remote work suits most office jobs.

    Stacked opinion phrases waste words and look like padding. One signal of opinion per sentence is enough.

  • Not thisBecause of the traffic. Many people arrive late.

    ThisBecause of the traffic, many people arrive late.

    A subordinate clause on its own is a fragment. Under time pressure candidates start a ‘because’ clause and then full-stop it.

  • Not thisAnswering only the first half of a two-part prompt.

    ThisOne paragraph for each half, even if the second is shorter.

    Task fulfilment is checked before anything else. A brilliant answer to half a question is still half an answer.

  • Not thisNowadays in modern society, the world is changing very fast in many aspects.

    ThisMost offices in my city now let staff work from home at least one day a week.

    Empty openings burn twenty seconds and say nothing. Start with something concrete and specific to the prompt.

  • Not thisThe government should to increase the budget.

    ThisThe government should increase the budget.

    Modal verbs take the bare infinitive. This slip appears constantly in opinion writing because ‘ought to’ and ‘have to’ sit nearby in the mind.

  • Not thisPeoples thinks that public transport is expensive.

    ThisPeople think that public transport is expensive.

    Two errors in three words: ‘people’ is plural already, and a plural subject takes ‘think’. Both are on the checking list for your last thirty seconds.

  • Not thisRepeating the prompt sentence as your first line.

    ThisStating your own position as your first line.

    Copying the prompt adds words but no content, and it delays the point the whole answer has to support.

Frequently asked questions

How long should my extended answer be?

Long enough to develop two or three points properly. Writing more than you can check is a poor trade: accuracy and organisation matter more than word count.

Can I use personal examples?

Yes, and they are usually the best choice. A specific example from your own life is quick to write, easy to keep grammatical and more convincing than an invented figure.

Is it worth memorising linking phrases?

A small set is worth having automatic: for instance, in addition, as a result, on the whole, whereas. Beyond that, memorised phrases start to sound bolted on and take space your own ideas need.

Should I write an introduction and a conclusion?

Yes, but keep both to one sentence. State your position at the start and sum it up at the end; the marks are in the middle paragraphs where you develop and support your points.

What should I check in the last thirty seconds?

Three things only: third-person -s on present-tense verbs, plural -s on nouns, and missing articles. Trying to reread everything means fixing nothing before the timer stops.

Does this writing go anywhere beyond the score?

Samples of your written and spoken performance can be shared with the institutions you send results to. Write as if a human admissions officer will read it, because one may.
