Duolingo English Test common mistakes
Duolingo English Test · Understand the traps and how to avoid them.
On 'Read and Select' items, clicking words that merely look English (e.g. invented forms built from real roots) while skipping genuine low-frequency words like 'ubiquitous' or 'admonish' because they feel unfamiliar.
The item is fast and the only available strategy is a familiarity feeling, so candidates substitute 'does this look like a word I have seen?' for 'can I define and use this word?'. Plausible morphology defeats that shortcut.
What to do instead
Apply a two-second test before selecting: silently put the word in a sentence or give a synonym. If you cannot, do not select it. Separately, drill common Latin/Greek roots and suffixes so real academic vocabulary stops feeling strange.
Leaving gaps blank, or entering only one or two letters, on 'Read and Complete' passages, usually the last four or five gaps of the passage.
The section runs on one overall timer and candidates treat each gap as a mini-puzzle worth solving perfectly, so the early gaps absorb the clock and the tail of the passage is abandoned.
What to do instead
Cap each gap at roughly 10-15 seconds, then type a best-guess word or at least the letters you are confident about and move on. Return only if time remains; a partial word can still earn credit, a blank cannot.
Filling in each missing word in a passage by looking only at the sentence containing the gap, producing answers that are grammatical locally but contradict the passage's tense, subject or argument.
Candidates treat the task as isolated vocabulary recall rather than discourse repair, and reading the whole text first feels like wasted time.
What to do instead
Do a 20-second skim of the full passage before writing anything, note the tense and topic, then answer gaps left to right, re-reading the preceding and following sentence for each one. Check afterwards that the completed text reads as one coherent whole.
On 'Listen and Type', stopping mid-sentence to repair a missed word, then losing the rest of the audio and typing a shortened or invented sentence.
Dictation is unfamiliar and working memory is overloaded; the instinct is to perfect the beginning before moving on, but the audio does not wait.
What to do instead
Listen to the whole utterance first, hold it in two or three chunks, and type the chunks as they are, leaving a placeholder or gap for anything missed. Reconstruct the missing word at the end from grammar and collocation rather than freezing.
On 'Listen and Select', choosing words that fit the topic of the recording rather than words actually spoken, and hovering on each item until the audio has moved on.
Top-down expectation is faster than phonetic decoding, so the brain 'hears' the predicted word; hesitation compounds the problem by letting the recording advance.
What to do instead
Decide within about two seconds per word and commit. Judge only what you heard, not what the topic implies, and when unsure ask whether the word's stress pattern and vowel sounds matched the audio, not whether it belongs in the context.
Giving minimal replies in Interactive Listening tasks - a single word, 'yes', or a restatement of the prompt - without addressing the speaker or adding any content.
Candidates read the task as a listening comprehension check and do not realise their own spoken turn is scored for grammar, range and appropriateness, not just for understanding.
What to do instead
Answer in a full sentence that directly responds, then add one reason, detail or question. Practise the pattern 'direct answer + because + specific detail' out loud until it is automatic.
Reading aloud at speed in a low, trailing voice, running sentences together without pausing at commas and full stops, or speeding up over words whose pronunciation is uncertain.
Nervousness about the microphone plus the belief that fast equals fluent; rushing also hides mispronunciation in the moment, but it is exactly what the scorer penalises.
What to do instead
Record yourself weekly and play it back at arm's length. Aim for a deliberate pace with audible consonants, a clear pause at every punctuation mark and a falling tone at full stops. Do the microphone check and speak across the mic, not into it.
On 'Speak about the photo', listing the visible objects for ten to fifteen seconds and then stopping early or trailing into silence for the remaining time.
There is no plan for open-ended speech, so once the obvious nouns are exhausted the candidate has nothing prepared and silence feels safer than error.
What to do instead
Use a fixed three-part frame every time: overall scene and impression, then two or three specific details with speculation about them, then an inference or personal connection. Rehearse 90-second monologues on random photos so the frame, not the content, is what you have memorised.
Producing two or three short, simple sentences on 'Write about the photo' and hitting submit with a large share of the time still unused and no proofread.
Candidates mirror texting habits, assume length is irrelevant, and do not know their typed response is scored on grammatical range and complexity as well as accuracy.
What to do instead
Target a full response built from a plan: two sentences of description, one of speculation, one of opinion. Use at least one subordinate clause and one less common word. Reserve the final 60 seconds to check subject-verb agreement, articles, spelling and full stops before submitting.
Opening speaking and writing samples with rehearsed phrases such as 'In today's modern world, technology plays a vital role' or inserting advanced words chosen for impressiveness rather than meaning.
Prep advice encourages memorised templates, and candidates believe rare vocabulary alone raises the score, so the answer drifts away from the specific prompt.
What to do instead
Make the first sentence prompt-specific by naming the actual topic, and drop any word you would not use correctly in speech. Prioritise accurate collocation and precise ordinary words over impressive ones; before submitting, cut anything that reads as a template.
