About LevelUpESL

LevelUpESL is a free English grammar practice resource for learners worldwide. Our quizzes cover all major grammar topics aligned to the Common European Framework of Reference for Languages (CEFR), from A1 (Beginner) to C2 (Proficient). Every quiz gives you instant feedback on each answer, plus a clear explanation so you understand the rule — not just the result.

We built LevelUpESL because most grammar quiz sites are outdated, cluttered with ads, or make you wait until the end to see how you did. We think learning works better with immediate feedback. That's why every question tells you right away whether you got it right, shows you the correct answer if you didn't, and explains the grammar rule in plain English.

All quizzes are free, forever. No account needed. Just pick your level, start a quiz, and level up.
