English grammar test

It is a free, interactive grammar quiz: fifteen multiple-choice questions drawn at random from a bank covering tenses, articles, prepositions, agreement, conditionals, modals, pronouns, quantifiers and more. After each answer you get an instant explanation, and at the end a score, an estimated level, and a link to study whatever you got wrong.

Fifteen questions, pulled at random from a bank of 45 so a retake is not the same test twice. Most people finish in three to five minutes. There is no timer — read each sentence carefully.

Yes. It runs entirely in your browser, there is no sign-up, and you can retake it as many times as you like. Nothing is charged and no account is created.

19 topics: verb tenses, articles (a/an/the), prepositions, subject–verb agreement, comparatives and superlatives, first, second and third conditionals, wishes, modal verbs, pronouns, countable/uncountable quantifiers, adjectives versus adverbs, gerunds, infinitives and “used to”, phrasal verbs, the passive voice, reported speech, relative clauses, question tags, indirect-question word order and linking words.

It spans beginner to advanced. The easier questions sit around A2–B1 and the harder ones around B2–C1, so it gives a useful reading whether your English is still developing or already strong. Your result names the band your answers point to.

It gives an estimate. Score 90%+ and it points to C1–C2, 75%+ to B2, 55%+ to B1, 35%+ to A2, and below that to A1. It is a quick self-check on grammar alone, not a full CEFR assessment — for a broader estimate use the English level test.

The DET does not have a section labelled “grammar”, but grammar runs through almost every task — Fill in the Blanks, Read and Complete, Interactive Writing and the speaking tasks all reward correct structure. Sharpening the rules here feeds directly into those. See the question types for how each task works.

Yes, as often as you like. Each attempt draws a fresh set of fifteen from the bank and reshuffles the answer choices, so retaking is real practice rather than memorising positions.

No. The test needs no email, no login and no payment. Your answers stay in your browser and nothing is stored on a server.

One point per correct answer out of fifteen, shown as a total and a percentage. The tool also tracks which topic you missed most and names it as your weakest area, linking to that topic’s rule and examples on this page — and to a full guide on this site where one covers it.

No single quiz is. Grammar is one pillar; the Duolingo English Test also measures vocabulary, reading, listening, writing and speaking. Use this to firm up structure, then take a full DET mock test for a four-skill, eight-subscore result.

Twelve or more out of fifteen (80%+) is a strong result and points to upper-intermediate grammar or better. Anything lower simply shows you which topics to review — the tool tells you which one to start with.

Yes. It is built to work on phones, tablets and computers — tap an answer, read the explanation, move on. Nothing needs to be installed.

Every topic has its rule and an example in the “Grammar rules at a glance” table on this page, and your result links straight to it. Three topic groups also have full guides: English tenses for tense questions, parts of speech for articles, prepositions, pronouns, adjectives, adverbs and linking words, and phrasal verbs for verb-plus-particle questions.

No. This is an independent practice tool made to help you learn, not an official Duolingo product, and the level it reports is an estimate rather than a certified score. Only a real test taken through Duolingo produces an official result.

Yes, in two ways. During the quiz every answer is marked straight away with a one-line explanation, right or wrong. Below the quiz, a sample of questions from the same bank — one per topic — is printed with its answer and the reason, so you can study the key directly. Try the quiz first, since reading the key beforehand spoils a few questions.

At B2 you should control the passive voice, reported speech, all three conditionals, wishes, modals of deduction (must / can’t), question tags and indirect questions, on top of the B1 core: the present perfect, gerunds and infinitives, and relative clauses. The “Grammar by level” table on this page lays out A1 to C2, based on common CEFR grammar descriptors.

It can work as a quick one. The questions run from A2 to C1 and your score maps to an estimated level, which is often enough to choose a course or a starting point. It is not a formal placement exam, though — schools that place students officially use longer tests that also measure listening, speaking and writing.

Yes. The sentences are everyday adult English — work, study, travel and news — rather than classroom exercises for children, and the bank reaches C1-level structures such as the third conditional and modals of deduction. It suits adults preparing for exams, study abroad, work or simply checking how accurate their English is.

The ones this bank targets most: mixing the past simple and present perfect (“I have seen it yesterday”), missing or wrong articles, the wrong fixed preposition (“interested about”), agreement slips (“the news are”), “much” with countable nouns, and the wrong verb form after verbs like “enjoy” or “suggest”. Each has a rule and example in the table on this page.
