Duolingo English Test Study Tips from Top Performers

1Use the official Test Structure article first so you recognize every task type and do not waste energy figuring out directions on test day.
2For reading tasks, slow down enough to check spelling, word form, nearby grammar, and whole-sentence meaning before answering.
3For listening tasks, focus on meaning units: subject, action, object, time, reason, and next step. In dictation, missing a full word is usually worse than a small typo.
4For interactive listening summaries, write only supported information: who spoke, what the issue was, what details mattered, and what outcome or next step was agreed.
5For speaking and writing, answer the prompt directly, add specific details, organize your response clearly, and avoid memorized templates that do not fit the task.
6Take the official free practice test more than once to experience adaptive delivery and receive an estimated score range.
