DET Mock Test 3
The third disjoint set, with its own passages, dictations, conversations and prompts. Same difficulty range and the same scoring, so its score compares directly with the others.
- About an hour, eight sections, run in the real order
- All 13 question types — nothing here appears in the other six tests
- Eight subscores and per-answer feedback the moment you finish
Mock Test 3 is a full sitting, not a sample. It opens with a short start screen — no camera, no permission prompts — then runs the eight sections in the order Duolingo runs them and ends with a scored report. Budget an uninterrupted hour, and have a microphone ready for the speaking section, where your browser asks for it.
Free for a limited time. No card, and no account needed to take it or to see your score.
What Mock Test 3 is built from
Eight sections, in the order you will meet them on the day. Everything in the right-hand column belongs to Mock Test 3 alone — none of it appears in the other six tests — and where a section draws from a pool, the engine picks what suits the level you are working at, so two people taking this test will not meet exactly the same items, or even the same number of them.
| Section | Task types | In Mock Test 3 |
|---|---|---|
| 1 · Read & Select | Read & Select | 15–18 of its 67 real and invented words, 5 seconds each |
| 2 · Fill in the Blanks | Fill in the Blanks | 6–9 of its 20 sentences |
| 3 · Mixed Language Skills | Listen & Type, Read & Complete | 9–15 items in 24 minutes, from its 18 passages and 29 audio clips |
| 4 · Interactive Reading | Interactive Reading | Two of: Fewer bins, cleaner park; The village shop that reopened; A bridge for animals; Phones in a hospital waiting room — five steps each |
| 5 · Interactive Listening | Interactive Listening | Two of these conversations: You visit a walk-in clinic about a sore wrist and speak with the nurse at the desk. You call your landlord about a leak in the kitchen of your flat. You are talking with your professor about studying abroad. You are asking a colleague to swap shifts with you next week. You call a garden centre about a delivery of plants and compost that has not arrived. |
| 6 · Writing | Write About the Photo, Writing Sample | Four written responses, two of them about photographs from this test’s three: An empty, bright modern office lounge; An overhead view of three plates of food on a grey wooden table; A narrow dirt path curving into a dense forest of tall straight trees |
| 7 · Speaking | Speak About the Photo, Interactive Speaking | The remaining photograph, described aloud, then a spoken conversation |
| 8 · Writing & Speaking Sample | Writing Sample, Speaking Sample | 8 minutes on open prompts |
When to take Mock Test 3
Keep it for the final week as a dress rehearsal a few days before the real test: one uninterrupted hour, at the time of day you plan to sit the DET, phone away. A result in line with your target is the signal to buy the real test; a gap is the signal to wait.
That order is a suggestion, not a requirement: the seven tests are equated — a score means the same on each — so any of them can come first. What matters is leaving enough work between sittings for the next score to mean something.
What to bring, and what you get
Bring an unaided hour and finish every task. You leave with a predicted overall and all eight subscores — see the sample report — and the mock tests page covers getting a number worth trusting. The official test costs $70 USD; find your weak spots before you pay for it.
Start a practice test
An hour under real conditions, all eight subscores, and feedback on every written and spoken answer.
