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 larger bank 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.

Verb tenses, articles (a/an/the), prepositions, subject–verb agreement, comparatives and superlatives, first and second conditionals, modal verbs, pronouns, countable/uncountable quantifiers, adjectives versus adverbs, gerunds and infinitives, and common phrasal verbs.

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, with a link to the guide that 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 question is tagged by topic, and your result links to the matching guide — English tenses for tense and conditional questions, parts of speech for articles, prepositions, agreement and pronouns, 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.
