Best Free Duolingo English Test Mock Tests 2026
Quick answer
Searching for the best free Duolingo English Test mock tests 2026 can lead to offers that look similar but provide different things. One service supplies a complete attempt; another supplies question drills; a third asks for payment before showing detailed feedback. This guide compares those differences so you can choose a resource without paying for a feature you do not need.
Checked October 5, 2026. This is an editorial comparison of public official and provider documentation, not a hands-on score-accuracy study. “Best” describes the use case we recommend. We have not purchased or independently validated these providers’ scoring systems. TypoGrammar is an independent learning site, not Duolingo. The cover is an AI-generated illustration of a study setup.
Free DET mock tests and practice options compared
| Option | Best use | What is free? | Account and limits |
|---|---|---|---|
| Official DET practice | First benchmark and repeated format practice | Repeatable adaptive practice with an estimated range | Account required; result is not certification |
| Gurully | Trying a third-party mock interface | A free mock is advertised | Registration required; verify the allowance in your account |
| DETPractice | Question-type drills | 300+ practice questions with basic explanations | The free tier excludes instant feedback and AI correction; do not assume full mocks are included |
| Arno | Repeated question practice | Unlimited practice is advertised | The provider lists mock tests, detailed feedback and study plans as premium features |
The first two entries are the mock-test options in this comparison. The last two are included as free practice alternatives, with their limits stated explicitly. Provider claims describe their own products; they do not establish that a third-party score matches the certified exam.
1. Official DET practice: best first benchmark
Duolingo’s practice-test documentation describes a free, repeatable test with the same question types and adaptive experience, an estimated score range, and a duration of about 45 minutes. Create an account through the official preparation page to begin. This is our recommended baseline because the exam provider maintains it.
Use a first attempt to notice where your performance breaks down. Did you lose time reading instructions? Did you understand the prompt but struggle to explain an example? Did spelling errors change the meaning of a listening answer? Record these observations as soon as you finish. A score alone does not tell you which activity to do tomorrow.
For later attempts, keep conditions reasonably consistent. If one session includes a dictionary and pauses while another does not, comparing the two results tells you little about progress. Treat a new attempt as a check on the skills you have practised, rather than an opportunity to chase a more flattering number.
2. Gurully: a free third-party mock to try
Gurully’s DET page advertises a free mock after account creation, with a test interface, AI scoring and a subscore breakdown. Its instructions ask users to select DET, register, choose the available free mock and review the report afterward. The public page does not establish an unlimited free allowance, so check what your dashboard includes before beginning.
Our suggested use is a second interface for practising pace and reviewing responses. If its estimated score differs from your official practice result, do not assume the higher number is correct. Look for agreement about the underlying issue: unfinished answers, weak development or repeated language errors. We have not independently tested Gurully’s score prediction.
3. DETPractice and Arno: free drills with upgrade limits
DETPractice’s free-versus-premium table lists 300+ free questions across question types and basic explanations. It places instant feedback, practice records and AI correction outside that free tier. That makes the public free offer relevant for familiarization, but it does not justify calling every mock or report on the platform free.
Arno’s public FAQ describes unlimited free practice and distinguishes it from subscription features, including mocks, detailed feedback and personalized plans. Use its free questions to work on a specific skill; inspect current account terms before assuming a full scored mock is available at no cost.
A sensible free routine can combine a benchmark attempt with short drills. For example, if your written answers are vague, spend the next session turning broad claims into specific examples. More full tests will not automatically teach that skill. Our DET writing guide and Read and Select practice provide additional independent exercises.
How we chose the best free options
We prioritized clear public access terms, relevance to DET preparation, an identifiable purpose, and honest boundaries between practice and certification. We did not award numerical ratings or rank services by unverified accuracy percentages. An attractive report is useful only if it helps you make a better next study decision.
- Format: compare current task coverage with official instructions, including Interactive Speaking.
- Access: confirm whether “free” means one mock, repeatable tests, sample questions or a temporary trial.
- Feedback: find out whether the report explains mistakes or only gives a number.
- Scoring: distinguish a provider estimate from an official certified score.
- Payment: check whether results, extra attempts or detailed corrections require an upgrade.
The official test-structure page is the reference for current tasks. It describes an adaptive exam, includes Interactive Speaking, and asks candidates to reserve about one uninterrupted hour for the certified test. A practice product’s length or presentation should not be treated as the official test specification.
Free vs paid DET mock tests: when is an upgrade useful?
Free practice is a reasonable place to begin. Consider a paid DET mock-test package, preparation course or tutor only when you can name the missing support. Someone who repeatedly runs out of time may benefit from timed rehearsal. Someone whose ideas are difficult to follow may need feedback on a complete answer, followed by a chance to revise it.
Before buying, inspect a sample report. Does it quote the sentence that caused the problem? Does it explain a correction? Can you revisit your response? Compare the access period, number of attempts, reviewed responses and cancellation terms. A large question count is not the same as individualized teaching, and a prediction does not become official because you paid for it.
Before you register for the certified test
A seven-day mock-test review plan
This is a suggested review cycle, not a promise of a particular score in one week. If your language level is well below your target, repeat the skill-building stage for longer. The goal is to learn from a mock instead of simply taking another one.
- Day 1: establish a baseline. Take an official practice attempt and record your main difficulties.
- Day 2: sort the errors. Separate vocabulary gaps, misunderstood instructions, incomplete ideas and timing problems.
- Day 3: repair comprehension. Review reading evidence and listening mistakes, then try unfamiliar material.
- Day 4: record speaking. Check whether you answer directly, support the point and finish sentences clearly.
- Day 5: revise writing. Improve one response, then answer a fresh prompt without copying your revision.
- Day 6: reassess. Complete another practice attempt after review and compare both the result and your experience.
- Day 7: choose the next step. Continue targeted study, seek specific feedback or prepare your equipment if you are ready.
For a longer schedule, use our 14-day DET study plan. Duolingo’s readiness guidance also recommends improving everyday English and checking your room and equipment before test day.
How to interpret a mock-test score
Imagine that your program requires 120 and your practice result spans 115–125. The target is inside that range, but this does not demonstrate that you will earn 120. Review the weakest tasks and gather more evidence from fresh responses. If the program also specifies subscores, a single overall estimate cannot prove that you meet them.
A useful error log has four columns: task, problem, correction and next exercise. For instance: “spoken opinion; repeated my opening; add one concrete example; record a new answer about a different topic.” This turns feedback into a repeatable action. Do not memorize a model answer and mistake familiarity with that answer for stronger English.
Frequently asked questions
What is the best free Duolingo English Test mock test in 2026?
Our first choice is the official DET practice test for format familiarity and an estimated score range. Gurully also advertises a free mock after registration. Choose by the task you need to practise, and check current access limits.
Is the official Duolingo English Test practice test free and unlimited?
Yes. The official help page says the practice test is free, requires an account and can be repeated as often as you like. It takes about 45 minutes.
Can I take a free DET mock test without login?
The official practice test requires an account, and Gurully also requires registration for its free mock. Public example questions can support study without reproducing a complete scored test.
Can I send my mock-test score to a university?
No. A practice estimate is not a certified result. Follow the university’s instructions for submitting an accepted English proficiency test result.
Are Arno and DETPractice completely free?
Both offer free practice, but their public pages distinguish free access from premium features. Arno lists mock tests and detailed feedback among subscription features; DETPractice lists limits on its free questions and feedback. Check the current plan before signing up.
How many DET mock tests should I take?
There is no fixed number that guarantees readiness. Our suggested approach is one starting attempt, focused practice on the weaknesses it reveals, and a fresh attempt after review. Repeating tests without correcting mistakes is a weak study strategy.
