Common Mistakes to Avoid in the Duolingo English Test

May 2, 2025

The Duolingo English Test (DET) is a popular and accessible option for many individuals looking to prove their English language proficiency. With its quick, online format, it offers convenience for test-takers worldwide. However, like any exam, success requires preparation and attention to detail. To help you perform at your best, it's crucial to be aware of common mistakes that many test-takers make during the Duolingo English Test.

In this blog, we'll walk through some of the most frequent mistakes and provide tips on how to avoid them to ensure you achieve the best possible results.

1. Not Understanding the Test Format

One of the most common mistakes is failing to fully understand the format of the Duolingo English Test. The test includes multiple types of questions that assess your reading, writing, speaking, and listening skills. Without knowing what to expect, you may find yourself unprepared for certain sections.

How to Avoid It:

  • Familiarize yourself with the test structure by visiting the official Duolingo website and reviewing sample questions.

  • Take a few practice tests to get comfortable with the different types of questions and the timing.

2. Not Using Proper Speaking Techniques

The speaking section of the Duolingo English Test evaluates your ability to clearly pronounce and articulate English words and sentences. Many test-takers make the mistake of speaking too quickly, too slowly, or unclearly, which can negatively affect their score.

How to Avoid It:

  • Speak clearly and at a moderate pace.

  • Avoid rushing through the responses. Make sure each word is pronounced correctly.

  • Try practicing speaking English regularly to build confidence and fluency.

3. Overthinking the Answer

Another common mistake is overthinking the questions. This happens especially in sections that involve filling in the blanks, completing sentences, or answering short questions. Some test-takers second-guess themselves, which leads to errors or missed opportunities to answer correctly.

How to Avoid It:

  • Trust your instincts. The Duolingo Test is designed to be straightforward, so don’t waste time overanalyzing the questions.

  • Read the instructions carefully, but respond quickly without dwelling on each question for too long.

4. Not Paying Attention to Instructions

Many test-takers overlook the instructions for each section or question, which can lead to mistakes in answering. For example, some questions may ask you to type a sentence, while others may require you to select the correct word or image. Misunderstanding the instructions can lead to answers that don't meet the criteria, resulting in lower scores.

How to Avoid It:

  • Read each set of instructions carefully before proceeding.

  • Pay attention to key details such as word count or specific tasks you are asked to complete.

5. Ignoring the Time Limit

The Duolingo English Test is timed, and while it is not extremely fast-paced, managing your time effectively is crucial. Many candidates make the mistake of spending too much time on one question and rushing through the rest of the test.

How to Avoid It:

  • Practice with timed tests so you become more accustomed to managing your time.

  • If you’re unsure about a question, move on and return to it later if you have time.

6. Not Preparing for the Writing Section

The writing section of the Duolingo Test requires you to construct coherent, well-organized responses to prompts. A common mistake is neglecting this section in preparation, leading to poorly written or incomplete responses.

How to Avoid It:

  • Practice writing in English, focusing on grammar, spelling, and sentence structure.

  • Write out full responses, even if they are brief. Make sure your answers are clear and relevant to the prompt.

7. Not Taking Advantage of the Practice Test

Many candidates overlook the importance of taking the practice test. The Duolingo English Test website offers a free practice test that closely mimics the real exam experience. Skipping this step can leave you unprepared for the actual test conditions.

How to Avoid It:

  • Take the free practice test on Duolingo’s website.

  • Simulate exam conditions by practicing in a quiet environment and sticking to the allotted time limits.

8. Poor Test Environment

The Duolingo English Test is taken online, which means your test environment plays a vital role in your performance. Distractions, poor internet connection, or technical issues can all lead to mistakes or a less-than-optimal experience.

How to Avoid It:

  • Ensure that you are in a quiet, distraction-free environment.

  • Check your internet connection and ensure your device meets the technical requirements for the test.

  • Close any unnecessary applications or tabs on your computer during the test.

9. Not Using the "Pause" Option Wisely

While the Duolingo test allows you to pause the test briefly, some candidates make the mistake of using this option too frequently, which disrupts their focus and test flow.

How to Avoid It:

  • Use the pause option sparingly. Try to complete as much of the test as you can in one sitting to maintain your momentum.

  • If you do need to pause, use it for genuine needs, such as a short break or adjusting your setup.

10. Being Unprepared for the Listening Section

The listening section evaluates your ability to understand spoken English, which can be challenging if you haven't practiced your listening skills. Many candidates make the mistake of not preparing enough for this section, leading to misunderstandings.

How to Avoid It:

  • Regularly practice listening to English audio materials, such as podcasts, movies, or news.

  • Pay attention to different accents, as the Duolingo Test may feature various English accents.

Conclusion

While the Duolingo English Test is designed to be accessible and user-friendly, it’s still important to avoid common mistakes in order to achieve your best possible score. By understanding the test format, preparing for each section, and managing your time effectively, you can confidently approach the exam and maximize your chances of success.
