How Good Is Your Grammar? Free 30-Question Grammar Test

This is not a vocabulary test and not a reading test: there are no passages, no word-meaning questions and no comprehension items on an unfamiliar topic, only standalone sentences. It also does not produce a CEFR level or any single English-proficiency band — for that broader picture across grammar, vocabulary, reading and everyday workplace usage, the English Proficiency Test is the right instrument; this one isolates grammar accuracy on its own and goes no further. It says nothing about speaking or listening, and nothing about writing quality beyond mechanical correctness: a grammatically flawless sentence can still be unclear, badly organised or pitched at the wrong register for its reader, and none of that is visible here. It is a self-scored accuracy check, not an accredited certification and not equivalent to a professional proofreading or copy-editing qualification.

Answer all thirty questions and you get an overall accuracy band, from Rules Still Settling through to Near-Perfect Accuracy, plus four separate area scores, so you can see which one is holding the overall band down rather than guessing at it. There is no email address to enter and no account to create before you see that result. The test itself is untimed, though most people finish in around seven minutes, since each item is one sentence to complete rather than a passage to read first. Where a low area score surprises you, the write-up names the pattern behind it in plain language — which construction keeps catching you out — rather than leaving you with a bare number and no way to act on it.
