The build a sentence task is the first writing exercise on the Duolingo English Test, and mastering it sets the tone for your entire writing score. This guide breaks down what to expect, how the task is graded, and four practical tips to nail the grammar puzzle every time.

What is the writing section of the Duolingo English Test?

The writing section is linear, not multi-stage adaptive like reading or listening. Every test taker sees the same questions in the same order, but the tasks are flexible enough to reveal a wide range of proficiency levels.

You get roughly 23 minutes to answer 12 questions spread across three task types. The skills measured reflect real-world writing: drafting emails, posting on social media, sending instant messages, and completing course assignments in offices, labs, and classrooms.

What are the three writing tasks on the Duolingo English Test? Build a sentence, write an email, and write for an academic discussion. Each one targets a different communication scenario you face in school or work.

How long do you have for the writing section?

You have around 23 minutes to complete all 12 writing prompts. That averages just under two minutes per item, so pacing matters as much as accuracy.

How does the build a sentence task work?

You receive an introductory question or statement, followed by a scrambled group of words and phrases. Your job is to drag those pieces into the blanks to form a grammatical, contextually appropriate response.

Here's the catch: sometimes there are extra words or phrases that don't belong in the final sentence. The test won't warn you. You'll notice it because the number of options exceeds the number of blanks.

For example, if the prompt is "Excuse me, do you work here?", the correct response would be "What can I do to help you?" In another item, the answer might be "The tour guides who showed us around the old city were fantastic", where a distractor like "whos" is included to throw you off.

Is there partial credit on the build a sentence task? No. Answers are either right or wrong, so every word placement counts. One misplaced phrase costs you the entire item.

What kind of sentences should you expect?

Expect short, conversational exchanges and descriptive statements. The grammar tested ranges from basic subject-verb agreement to relative clauses, like the "who showed us around" example.

How can you score higher on the build a sentence task?

Four habits will improve your accuracy on this exercise:

• Read every element carefully: the first sentence of the dialogue, the words already placed in the incomplete sentence, and all the options provided.
• Build a response that is grammatically correct and matches the tone or intent of the first sentence.
• Review the finished sentence before submitting. A quick reread often catches a misplaced article or verb.
• Stay alert for extra words or phrases that don't belong. If the option count exceeds the blanks, a distractor is hiding among them.

Practicing with timed drills helps you internalize these checks so they happen automatically during the real exam.

Why does reading the prompt matter so much?

The first sentence sets the context. A question like "Do you work here?" signals that your response should be an offer or clarification, not a statement about yourself. Misreading the prompt usually leads to grammatically correct sentences that still miss the point.
