| Duolingo – Grammar Quiz |
| Improve your grammar skills with beginner to intermediate exercises designed to boost your performance in the Duolingo test. |
These quiz series are designed as an effective help for students to prepare for the Duolingo English Test (DET), focusing on the adaptive, integrated language skills required for university admissions and online certification, including vocabulary, grammar, reading, listening, and production.
They focus on high-frequency academic and conversational words, word families, missing letter completion, interactive reading tasks, listen-and-type exercises, and question types found across DET sections such as Read and Select, Listen and Type, Interactive Listening, and Fill in the Blanks. The quizzes are suitable for international students applying to universities that accept DET scores, test-takers seeking a fast, affordable alternative to other English exams, and ESL learners preparing for online adaptive testing formats.
Each quiz challenges learners to identify real English words, select correct spellings, complete missing letters in words, understand context from short passages, transcribe spoken sentences accurately, and avoid common mistakes in word recognition and grammar. Tests are presented in a multiple-choice format; only one answer is correct and will be highlighted in green once the student provides an answer.
These tests can be used in DET preparation courses, self-study routines, tutoring sessions, quick daily warm-ups, and as last-minute practice before test day. They are all provided for free — feel free to share them with friends and colleagues to support our work.
