7 Best Free English Grammar Exercise Websites in 2026 (Honest Comparison)

If you search "free English grammar exercises," Google gives you millions of results. Most look the same. Some haven't been updated since 2010. A few are genuinely excellent.

I've spent hours testing the most popular grammar exercise websites so you don't have to. Here's what I found — the good, the bad, and the surprisingly outdated.

What I Looked For

Not all grammar websites are created equal. I evaluated each site on six things that actually matter to learners:

• Exercise quality — Do they test understanding, or just memorization?
• Feedback — Do you get an explanation when you're wrong, or just a red X?
• Design & usability — Can you actually navigate the site without getting lost?
• Ads — Do pop-ups and banners make the experience painful?
• CEFR levels — Can you find exercises that match your level (A1–C1)?
• Mobile experience — Does it work well on a phone?

Let's go through the top seven, one by one.

1. British Council — LearnEnglish

Website: learnenglish.britishcouncil.org/grammar

Best for: Learners who want a trusted, institutional resource

The British Council is one of the most recognized names in English education. Their grammar section is well-organized by CEFR level (A1-A2, B1-B2, C1), and the explanations are clear and reliable.

What's good:

• Grammar explanations are concise and accurate
• Organized by CEFR level, so you can find your starting point quickly
• The British Council brand means quality control — no questionable grammar advice here
• Exercises include multiple choice and gap-fill formats

What's not so good:

• Each topic typically has just a few exercises — not enough for deep practice
• The design is clean but somewhat institutional; it doesn't feel engaging
• Mobile apps exist but feel dated and are due for a refresh
• No detailed explanation when you get an answer wrong — just correct/incorrect

Verdict: Great as a reference and starting point, but you'll need another site for serious practice volume.

2. Perfect English Grammar

Website: perfect-english-grammar.com

Best for: Learners who want thorough explanations alongside exercises

Run by Seonaid Beckwich, a teacher with decades of experience, this site has become a go-to for grammar learners worldwide. The explanations are among the best available online — detailed enough to actually learn from, not just skim.

What's good:

• Excellent, teacher-written grammar explanations
• Wide topic coverage (tenses, conditionals, passive, reported speech, and more)
• PDF worksheets available for offline practice
• A loyal community with an email newsletter

What's not so good:

• The website design feels like it was built in the early 2010s
• Exercises are mostly fill-in-the-blank with limited variety
• No instant feedback with explanations — you check answers at the end
• Navigation between related topics isn't always intuitive

Verdict: One of the best for learning grammar concepts, but the exercise experience itself is basic.

3. ego4u — English Grammar Online

Website: ego4u.com

Best for: Learners who want a huge pool of random practice sentences

ego4u has been around for a long time, and it shows — in both good and bad ways. The site claims 4,287 practice sentences across all tenses, which is impressive volume.

What's good:

• Massive exercise bank, especially for tenses
• Covers all 12 English tenses plus conditionals, passive, and more
• Lightweight and loads fast
• Includes vocabulary, writing tips, and even games

What's not so good:

• The UI looks like it hasn't changed since 2005
• Exercises are basic gap-fill with limited interactivity
• No CEFR level system — you're on your own figuring out difficulty
• The site structure can be confusing to navigate

Verdict: If you just want to hammer out hundreds of tense exercises and don't care about design, ego4u delivers. Otherwise, you'll feel like you've time-traveled.

4. Grammar Monster

Website: grammar-monster.com

Best for: Writers and advanced learners who want a grammar reference

Grammar Monster takes a different approach. It's less about exercises and more about understanding grammar at a deep level. With 278 grammatical terms in its glossary and 227 pairs of commonly confused words, it's a reference tool first and a practice platform second.

What's good:

• No ads inside lesson content (they're explicit about this)
• 137 interactive games and tests add variety
• Excellent for confused word pairs (affect/effect, their/there/they're)
• Teacher-friendly: shareable quizzes via WhatsApp or Google Classroom
• Run by a single dedicated creator (Craig Shrives), so content quality is consistent

What's not so good:

• Not designed as a systematic exercise platform
• Games are fun but light on grammar drilling
• More useful for native speakers polishing their writing than for ESL learners
• Topic organization is alphabetical, not by difficulty or learning path

Verdict: Brilliant reference resource. Less useful if you need structured, level-appropriate grammar exercises.

5. EnglishGrammar.org

Website: englishgrammar.org

Best for: Learners who want downloadable PDF exercises

With over 3 million subscribers, EnglishGrammar.org has built a huge following. Their exercise page offers gap-fill multiple choice exercises that you can complete online or download as PDFs.

What's good:

• Every exercise is available as a free PDF download
• Regular new content (exercises are dated)
• Covers grammar, vocabulary, and idiomatic expressions
• Clean enough layout with minimal distractions

What's not so good:

• Online exercises are basic — click and check, with minimal feedback
• The site promotes their "2026 Grammar Guide" aggressively via email opt-ins
• No CEFR level organization
• Exercises are listed chronologically, not by topic hierarchy — hard to find what you need

Verdict: The PDF downloads are genuinely useful, especially for teachers and offline study. The online experience is average.

6. test-english.com

Website: test-english.com

Best for: Learners preparing for English exams

test-english.com is one of the more modern-looking grammar sites, and it shows. The design is clean, exercises are organized by CEFR level (A1-B2), and the interactive format feels current.

What's good:

• Modern, responsive design that works well on mobile
• Organized by CEFR level — easy to find your starting point
• Multiple exercise types: multiple choice, gap-fill, and checkbox
• Visual feedback with color coding for correct/incorrect answers

What's not so good:

• Topic coverage is narrower than some competitors
• Some content pushes toward paid resources
• Explanations for wrong answers are limited
• Fewer exercises per topic compared to dedicated practice platforms

Verdict: A solid, modern option — especially if you're studying for an exam and want level-appropriate practice.

7. english-grammar.app

Website: english-grammar.app

Full disclosure: This is our site. But I'll apply the same honest criteria.

Best for: Learners who want structured practice with instant explanations

We built english-grammar.app because we were frustrated by the same things you probably are: grammar sites that look like they were built in 2008, exercises that just tell you "wrong" without explaining why, and no clear learning path from beginner to advanced.

What's good:

• Instant feedback with detailed explanations — every question tells you why an answer is correct, not just which answer is correct
• Modern UI — clean, card-based design that works seamlessly on desktop and mobile
• Three practice modes — multiple choice for quick practice, fill-in-the-blank worksheets for deeper recall, and downloadable PDF worksheets for offline study
• CEFR levels (A1–C1) across all 14 grammar categories
• No ads, no signup required — just open and practice
• 500+ exercises covering tenses, conditionals, modal verbs, prepositions, and more
• Bilingual support — topic names in both English and Chinese, useful for Chinese-speaking learners

What's not so good:

• We're newer and smaller than British Council or Perfect English Grammar
• Some advanced categories (C1) are still being expanded
• No community forum or discussion features (yet)
• No gamification elements if that's what motivates you

Verdict: If you want clean, explanation-rich grammar practice with zero friction, this is what we built it for. Try a set and see if it clicks.

Side-by-Side Comparison

*Grammar Monster has no ads in lesson content; ads appear in sidebars only.

Which Site Should You Use?

There's no single "best" grammar website — it depends on what you need:

• Want a trusted reference? → British Council
• Want the best explanations? → Perfect English Grammar
• Want massive exercise volume? → ego4u
• Want a grammar dictionary? → Grammar Monster
• Want downloadable PDFs? → EnglishGrammar.org
• Preparing for an exam? → test-english.com
• Want modern practice with instant explanations? → english-grammar.app

My actual advice: use two or three. Learn the grammar on one site, practice on another, and download worksheets from a third. The best combination depends on your level, your goals, and honestly, which design doesn't make your eyes bleed.

If you want to start practicing right now, here are some popular starting points:

• Present Simple exercises — the foundation of English grammar
• Prepositions: in, on, at — the three prepositions everyone gets wrong
• Modal verbs: can & could — ability and possibility
• First Conditional — if + will for real possibilities

Happy practicing. 🎯
