What is EngQuiz.Pro?
EngQuiz.Pro is a free tool for English learners at A2–C2 level who want focused, no-nonsense grammar practice. The goal is simple: get you into an exercise in two clicks, give you clear instant feedback, and help you understand why each answer is right or wrong.
There are no accounts, no paywalls, and no distractions. Your progress is saved locally in your browser so you can pick up where you left off at any time.
Who built this, and why
EngQuiz.Pro is built and maintained by Tinh Nguyen, the software engineer behind the platform, with grammar content reviewed by a qualified English language teacher. We started the project out of a shared frustration: most free grammar sites either bury practice behind newsletter sign-ups, hide answers behind paywalls, or rely on AI-generated copy that produces sentences a proficient speaker would never actually say.
So we built the site we wished existed as learners ourselves and, as teachers, the site we wished we could send our students to. Every grammar rule on this page was written or reviewed by a qualified teacher with classroom experience at the level it targets. Every exercise sentence was checked by a human for natural usage, not only grammatical correctness. And every page stays free, account-free, and tracker-light by deliberate choice, not because we plan to flip on a paywall later, but because we want the practice to stay one click away.
The team’s qualifications, examination specialisms, and full content review process are detailed in Our editorial team below. If you spot an error, want to suggest a topic, or would like to contribute, our contact details sit at the foot of this page; we read everything that comes in.

Grammar rules are verified against authoritative references including Swan's Practical English Usage and the British National Corpus.
Content quality & review process
Every exercise and blog article goes through a structured review before publication:
- Draft against the CEFR level descriptor: vocabulary and structures are matched to the target level.
- Grammar and naturalness check: a qualified teacher reviews each sentence for accuracy and natural usage.
- CEFR alignment verification: difficulty is calibrated against the official CEFR can-do descriptors.
- Publication and monitoring: learner feedback is reviewed regularly; reported errors are corrected within 24 hours.
The full sourcing standard (corpora, grammar references, difficulty calibration, and update cadence) is documented on the methodology page.
If you spot an error or an unnatural sentence, please let us know; corrections are prioritised immediately.
