AI-powered practice and scoring for the Duolingo English Test

Speaking and writing submissions are scored automatically, evaluating pronunciation, fluency, grammar, and content structure with suggestions for improvement.
Check your vocabulary level against CEFR bands and build word lists clustered around the question types you practise most.
