English Grammar Review: CEFR Levels A1 to C2 Explained

Grammar is often the most daunting part of learning English — and also the most misunderstood. Many learners spend years drilling irregular verbs when what they actually need is a structured English grammar review by CEFR levels: a clear map showing which structures belong to which level, what examiners expect, and where the gaps in your own knowledge sit. Whether you are preparing for a certification test, a visa application, or a university place, knowing your grammar level precisely changes everything about how you study.

What Is the CEFR and Why Does Grammar Matter?

The Common European Framework of Reference for Languages (CEFR) is an internationally recognised standard developed by the Council of Europe to describe language proficiency. It divides competence into six levels: A1, A2, B1, B2, C1, and C2 — from complete beginner to mastery.

Grammar is not a separate category in the CEFR; it is woven into every skill descriptor. When an examiner judges whether you are B1 or B2, they are partly assessing whether you can construct conditionals reliably, handle passive structures accurately, and deploy modal verbs with appropriate nuance.

A targeted English grammar review aligned to CEFR ensures you study what actually moves the needle — not random exercises that never appear in your target level.

Grammar by CEFR Level: A1 to C2 Breakdown

The table below gives a rapid overview of the core grammatical features expected at each level. Use it as your CEFR grammar checklist — tick off what you already control confidently.

A1 and A2: Building the Foundation

At A1, the focus is on producing short, predictable sentences using present simple and a small core of vocabulary. Learners can say "I work in a school" or "She likes coffee" but rarely manage complex clauses.

A2 expands that base significantly. The past simple unlocks storytelling ("We visited London last year"), while going to and will allow basic future plans. Conjunctions like because and so let learners link ideas — a critical step toward real communication.

Our complete English grammar guide covers A1 and A2 structures in depth, with example sentences for each pattern.

B1: The Intermediate Leap

B1 is where many learners plateau — and where grammar becomes genuinely complex. The present perfect ("I have worked here for three years") trips up speakers whose first language has no equivalent. Past continuous creates narrative layers ("I was cooking when she arrived"), and the first conditional introduces logical relationships ("If you study, you will improve").

Modal verbs at B1 go beyond simple ability. Must, should, might, and have to carry distinct meanings around obligation, advice, and possibility — and mixing them up changes meaning significantly.

For practical preparation, English test practice resources can help you consolidate B1 grammar before a formal assessment.

B2: The Turning Point for Certification

B2 upper-intermediate is the level most frequently required by European universities, HR departments, and many visa routes. At this stage, the CEFR grammar checklist includes:

• Passive voice across multiple tenses ("The report has been submitted")
• Second conditional for hypothetical situations ("If I had more time, I would study abroad")
• Third conditional for past hypotheticals ("If she had revised, she would have passed")
• Reported speech with appropriate tense backshift
• Defining and non-defining relative clauses
• Complex modal expressions (would have, might have, should have)

Accuracy at B2 does not mean perfection — errors still occur — but they should not impede understanding. To see how B2 grammar is assessed in practice, explore our B2 upper-intermediate English test.

C1 and C2: Advanced and Proficient Control

At C1, grammar becomes a stylistic tool. Learners use inversion for emphasis ("Rarely have I encountered such precision") and cleft sentences to foreground information ("It was the grammar that confused her"). The perfect aspect is deployed with full confidence across past, present, and future frames.

C2 represents near-native command. Ellipsis ("She can play piano, and so can he") and substitution reduce repetition naturally. The subjunctive appears in formal writing ("It is essential that he be present"), and register shifts between formal, neutral, and informal are managed effortlessly.

How to Conduct Your Own English Grammar Review

Knowing the framework is step one. Applying it to your own learning is where real progress happens. Here is a structured process:

1. Identify your current level. Take a benchmark assessment before anything else. Without knowing where you are, you cannot plan efficiently. Our free English level test places you on the CEFR scale within 20 minutes.

2. Audit your grammar knowledge against the checklist. Using the table above, go through each structure for your current level. Mark each as: confident / unsure / never learned.

3. Prioritise "unsure" items. These are your highest-value study targets — structures you have met but not yet internalised. Focus here before moving to the next level.

4. Study with level-appropriate materials. A B1 learner practising C1 texts builds bad habits through guessing. Use graded readers, practice exercises, and model sentences that match your current level.

5. Practise in context, not in isolation. Grammar sticks when used in real sentences. Write short paragraphs, record yourself speaking, and notice when you avoid a structure because you are unsure — that is the structure to study next.

6. Review and repeat at intervals. Spaced repetition is more effective than massed practice. Revisit grammar points after one day, one week, and one month.

7. Test again to measure progress. After 4–6 weeks of targeted study, repeat your benchmark test to confirm movement and update your study plan.

Common Grammar Mistakes at Each CEFR Level

Every level has predictable error patterns. Recognising them saves time.

• A1–A2: Forgetting the third-person singular -s ("She go to school"), incorrect word order in questions ("You like what?"), and mixing up have and be as auxiliaries.
• B1: Overusing the past simple instead of the present perfect ("I lived here for five years" when the person still lives there), and confusing make and do in fixed expressions.
• B2: Errors in conditional mixing ("If I would have known…" instead of "If I had known…"), and incorrect relative pronoun choice (which vs that in defining clauses).
• C1: Misjudging inversion context (using it in casual speech where it sounds unnatural) and inconsistent register across a single piece of writing.
• C2: Over-correction — adding complexity where simpler structures communicate more precisely — and rare errors with the subjunctive in formal writing.

Conclusion

A structured English grammar review by CEFR levels removes guesswork from your learning. Rather than studying everything at once, you focus on the specific structures that move you from your current level to your target level — efficiently and with measurable results.

Key takeaways:

• Grammar is embedded in every CEFR skill — it is not a separate subject but a foundation for reading, writing, speaking, and listening proficiency.
• Each CEFR level has a defined grammar profile — from basic sentence patterns at A1 to stylistic complexity at C2.
• A grammar checklist aligned to CEFR helps you audit your knowledge and prioritise study.
• Common error patterns are predictable — knowing the typical mistakes for your level lets you target them directly.
• Progress is measurable — benchmark tests before and after a focused study period confirm real improvement.
