The fastest way to internalize English grammar is not to read about rules — it is to apply them under real sentence conditions, see where you go wrong, and understand exactly why. This guide gives you 500 English grammar exercises organized by topic, CEFR level, and exam relevance, complete with answers and explanations for every question. Whether you are an A2 beginner forming your first complex sentences, a B2 learner preparing for IELTS Writing, or a professional brushing up for a TOEIC retake, you will find structured, purposeful practice here — not busywork.
What you will get from this page: a breakdown of all 10 grammar categories, sample practice questions with full explanations, a level-by-level practice roadmap, exam-specific guidance for IELTS and TOEIC candidates, and direct links to deeper topic guides across EnglishPractices.com.

Why Grammar Exercises Work Better Than Reading Rules
Most learners spend the majority of their study time reading grammar rules and far too little time practicing them. This imbalance is the single biggest reason progress stalls.
Hermann Ebbinghaus, the 19th-century cognitive psychologist, documented what is now called the forgetting curve: without active review, humans forget roughly 70% of new information within 24 hours of first exposure. Grammar rules are not exempt from this. You can read the rule for present perfect tense five times and still reach for past simple instinctively when speaking, because passive reading does not build procedural memory — the kind that operates under time pressure in a conversation or exam.
Active recall is what changes this. When you complete a grammar exercise — retrieve the rule, apply it to a novel sentence, and immediately check whether you were correct — your brain goes through a correction loop that rewires how the structure is stored. Cognitive science research on spaced repetition, widely documented and applied in language learning platforms globally, consistently shows that learners who practice retrieval in spaced intervals outperform passive readers in both accuracy and retention over time.
The 500 exercises at EP. are built on this principle. Each question isolates a single grammar point in a real sentence context. Each answer comes with a plain-English explanation, not a metalinguistic definition, but a direct explanation of why this form and not another. If you want the conceptual backbone before you start drilling, the complete English grammar guide maps every rule covered in this exercise set and serves as the pillar reference for everything below.
Sample Grammar Exercises with Answers and Explanations
The questions below are representative samples from the full exercise bank. Work through each one before reading the answer.
Tenses: Present Perfect vs Past Simple
This is the most frequently tested tense distinction on IELTS Writing Task 2 and one of the most common sources of error for learners whose first languages — including Chinese, Japanese, Korean, and Thai — do not have a grammatical equivalent of the present perfect.
Exercise 1
"She _______ (live) in London since 2019."
Answer: has lived Explanation: "Since 2019" signals a period extending from a past point to the present moment, which requires the present perfect. Past simple would imply the action is finished.
Exercise 2
"They _______ (finish) the project last Friday."
Answer: finished Explanation: "Last Friday" is a closed, specific past time reference. The past simple is the only correct form here. Present perfect cannot be used with a definite past time marker.
Exercise 3
"I _______ never _______ (see) anything like this before."
Answer: have never seen Explanation: "Never" without a fixed time reference signals a life experience up to the present, which requires the present perfect. This structure appears frequently in IELTS Reading and TOEIC Part 5.
For more depth on this area, see the guide to mastering present perfect, the dedicated present perfect tense exercises, and the past simple vs past perfect guide — three resources that together address the full spectrum of past-tense precision in English.
Articles: a, an, the, and Zero Article
Articles are notoriously problematic for speakers of languages without article systems, which includes Mandarin, Cantonese, Japanese, Korean, Vietnamese, Thai, and several others. They account for a high proportion of Band 6 to Band 7 IELTS Writing errors — a gap that targeted exercises can close efficiently.
Exercise 4
"He is _______ engineer working for _______ company in Singapore."
Answer: an / a Explanation: Both are first mentions of non-specific, countable nouns. Use the indefinite article. "An" precedes a vowel sound ("engineer").
Exercise 5
"_______ sun rises in _______ east."
Answer: The / the Explanation: "The sun" is unique — there is only one. "The east" refers to a known geographical direction. Both require the definite article.
Understanding article use depends heavily on understanding noun types. The countable vs uncountable nouns guide gives you the foundational distinction that determines which article is even possible in a sentence. The complete guide to articles in English then covers all four article options — including the often-overlooked zero article — with exercises.
Conditionals: Types 0 Through 3
Exercise 6
"If I _______ (know) the answer, I would have told you."
Answer: had known Explanation: This is a Type 3 conditional: an unreal past situation with a past consequence. The if-clause takes past perfect. Many learners incorrectly use simple past here ("If I knew…"), which changes it to a Type 2 — a different meaning entirely.
Exercise 7
"If water _______ (reach) 100°C, it _______ (boil)."
Answer: reaches / boils Explanation: Type 0 conditional. Scientific facts that are always true use present simple in both clauses. No hypothetical is implied; this is just cause and effect.
The full guide to conditionals in English covers all four types plus mixed conditionals, which regularly appear at B2–C1 level and in IELTS Academic Reading.
Passive Voice
Exercise 8
"Rewrite in passive voice: The committee approved the proposal yesterday."
Answer: The proposal was approved by the committee yesterday. Explanation: The object of the active clause becomes the subject. Past simple passive = was/were + past participle. "Yesterday" keeps the tense anchored in the past simple.
Exercise 9
"This building _______ (construct) in 1890."
Answer: was constructed Explanation: A specific past date requires past simple passive. "Has been constructed" would only be appropriate if the building's construction still has present relevance — an unlikely interpretation for 1890.
The passive voice guide on EP. walks through all passive tense forms with comparative active/passive examples.
Modal Verbs
Exercise 10
"You _______ bring your passport — it's required by law."
Answer: must Explanation: "Must" expresses strong obligation or a legal requirement. "Should" is advisory; "can" expresses permission or ability — neither fits a legal mandate.
Exercise 11
"She _______ be at home — her car is in the driveway."
Answer: must Explanation: Here "must" expresses logical deduction from visible evidence. This modal function — deduction vs obligation — is a high-frequency IELTS Reading comprehension test point.
The modal verbs guide covers all nine core modal functions: ability, permission, obligation, prohibition, deduction, probability, advice, possibility, and future prediction.
A Level-by-Level Practice Roadmap (A1 to C1)
Grammar practice without a plan produces inconsistent results. Think of CEFR levels the way a coach thinks about progressive training loads: start where you are, not where you want to be, and increase the challenge systematically.
| CEFR Level | Priority Grammar Areas | Recommended Weekly Questions |
|---|---|---|
| A1–A2 | Verb tenses, articles, basic prepositions | 30–40 questions |
| B1 | Modal verbs, Type 1 & 2 conditionals, gerunds vs infinitives | 40–60 questions |
| B2 | Passive voice, relative clauses, reported speech, Type 3 conditionals | 50–70 questions |
| C1 | Mixed conditionals, complex clause structures, register and formality | 70–100 questions |
Rushing to C1 exercises with unresolved B1 gaps is like skipping foundations in construction — the higher floors become unstable. Diagnose your weaknesses first, then drill them specifically.
If you prefer to self-study without a teacher, EP. offers a full structured method in the how to improve grammar without a teacher guide. It maps exactly how independent learners can use exercises, topic guides, and self-assessment to move between CEFR levels without classroom instruction.
Grammar Practice for IELTS and TOEIC Candidates
IELTS and TOEIC assess grammar in fundamentally different ways. Knowing which applies to you prevents wasted practice time.
IELTS Writing is scored across four criteria of equal weight. According to Cambridge Assessment English, Grammatical Range and Accuracy accounts for 25% of your Writing band score. Examiners look specifically for variety in structures and freedom from systematic errors — not perfection, but control. The most common grammar errors in IELTS Writing at Band 6–6.5 are tense inconsistency, article misuse, and incorrect relative clause punctuation.
TOEIC tests grammar discretely through Part 5 (Incomplete Sentences) and Part 6 (Text Completion). These sections test vocabulary-grammar overlaps: choosing the right preposition, selecting the correct verb form in a business email, identifying the appropriate conjunction in a formal report.
| Exam | High-Priority Grammar Topics | Format |
|---|---|---|
| IELTS | Present perfect, passive voice, conditionals, relative clauses | Writing Tasks 1 & 2 |
| TOEIC | Prepositions, determiners, modal verbs, reported speech | Parts 5 & 6 |
For TOEIC-specific preparation, the prepositions of time, place, and movement guide and the determiners in English guide address two of the highest-yield question types in Parts 5 and 6 respectively.
Grammar Errors That Cost Learners the Most Points
Based on patterns observed across global learner populations — including students in Vietnam, Thailand, South Korea, Japan, China, Mexico, and the UK — the following grammar points cause a disproportionately high number of errors in both exams and everyday writing.
Gerunds vs Infinitives "I enjoy to swim" is incorrect. "I enjoy swimming" is correct. The verb "enjoy" always takes a gerund. Many learners default to the infinitive because it feels like the base verb form, which is intuitive — but wrong for dozens of common verbs. The gerunds vs infinitives guide lists every verb that follows each pattern, including those that take both forms with a change in meaning.
Present Simple vs Present Continuous "I am knowing the answer" — stative verbs do not take the continuous form. "Know," "believe," "understand," "prefer," "own": these describe states, not actions in progress, and the continuous form is grammatically incorrect for them regardless of the situation. The present simple vs present continuous guide covers every stative verb category with examples.
Relative Clauses: The Comma Is Not Optional "The report which was submitted late caused problems" (defining — a specific report) versus "The report, which was submitted late, caused problems" (non-defining — adding information about a report already identified). The comma changes meaning. Removing or misplacing it is a B2 error that costs marks in IELTS Writing. The relative clauses defining vs non-defining guide addresses this distinction directly.
Reported Speech Tense Backshift "She said, 'I am tired'" becomes "She said that she was tired." The present simple in direct speech shifts to past simple in reported speech. Many learners skip this backshift entirely, especially in writing. The reported speech rules guide covers all tense and modal backshifts with before/after examples.
Word-Level Confusion: Affect vs Effect Not all grammar problems happen at the sentence level. "The policy affected the results" (verb) versus "The effect was significant" (noun). This distinction regularly appears in IELTS Academic Reading and TOEIC Part 7. The affect vs effect guide covers both the grammar rule and common usage traps.
It is also worth noting that English grammar is not a static system. Some rules that were taught as absolute in earlier decades are now considered overly prescriptive by modern style guides and usage research. The modern English grammar rules that have changed guide gives you an informed view of which rules still apply in formal contexts and which have evolved in real-world usage.
How EnglishPractices.com Builds These Exercises
EP. has been developing English learning resources for over 19 years, working with students from the UK, North America, Southeast Asia, East Asia, and Latin America. The 500-question exercise bank is not generated automatically or recycled from generic grammar books. Each question is:
- Tied to a specific CEFR-aligned grammar point with a single testable rule
- Written to reflect sentence types that appear in real IELTS, TOEIC, and workplace English contexts
- Accompanied by an answer and a plain-English explanation — because knowing you were wrong is only useful if you understand why
Every explanation avoids grammar jargon where possible and instead describes the logic of the rule in terms a learner can apply independently. This is the approach EP. has refined across thousands of individual students and corporate English programs worldwide. The homepage at EnglishPractices.com gives a full overview of available resources across all four skills.
Conclusion: Practice Is What Separates Understanding from Using
Reading a grammar rule gives you knowledge. Applying it under conditions that require retrieval — a timed exercise, an exam sentence, a business email — gives you skill. These are not the same thing, and no amount of rule-reading closes that gap the way practice does.
The 500 exercises here give you a structured, level-appropriate path from foundational accuracy to advanced grammar control. Use them in order for a comprehensive grammar review. Target specific categories if you have an identified weakness. Or work through ten questions a day as a daily warm-up — at that pace, the full set takes 50 days and covers every major grammar point you need for IELTS, TOEIC, or professional English.
