Common Grammar Mistakes That Lower Your IELTS Writing Score

Common Grammar Mistakes That Lower Your IELTS Writing Score

Do you feel that your ideas are strong but your IELTS Writing score doesn’t reflect your effort?  Have you ever received feedback like “good vocabulary, but grammatical errors lowered your band score”? Or do you spend hours practising essays yet struggle to score above Band 6.5 in Writing?

If your answer is yes, you’re not alone. Thousands of students face the same issue — their grammar silently pulls their IELTS Writing Score down. Even when your essay has great ideas and structure, grammatical mistakes reduce clarity and accuracy, two major scoring criteria in the IELTS exam.

The good news? Grammar isn’t a mystery. It’s a skill that can be learned and improved with the right training and practice. And that’s exactly what ThinkEnglish, one of the best IELTS coaching institutes in Chandigarh, focuses on — helping students strengthen grammar, refine writing style, and achieve higher bands confidently.

Why Grammar is Key to a High IELTS Writing Score

In the IELTS Writing test, grammar contributes 25% of your total score. Examiners assess your ability to use accurate sentence structures, tenses, punctuation, and articles. Good grammar doesn’t just make your writing error-free — it makes it sound fluent, logical, and professional.

Many students in India focus on ideas or vocabulary but overlook grammar accuracy. The result? Essays that look promising but lose marks for avoidable mistakes like tense shifts or missing articles.

At ThinkEnglish IELTS training in Chandigarh, trainers pay special attention to these details. Students learn how to improve grammar and sentence structure, use correct tenses, and maintain consistency throughout their essays — crucial skills for scoring Band 7 or higher.

Understanding the Role of Grammar in IELTS Writing

IELTS examiners evaluate four key areas:

  1. Task Achievement
  2. Coherence and Cohesion
  3. Lexical Resource (Vocabulary)
  4. Grammatical Range and Accuracy

Grammar affects every one of these. Poor grammar disrupts sentence flow and confuses the reader, while strong grammar enhances clarity. For example:

❌ “If people will exercise regularly, they can stay fit.”
✅ “If people exercise regularly, they can stay fit.”

The meaning is simple, but one grammatical slip can cost marks.

That’s why IELTS coaching in Chandigarh at ThinkEnglish focuses on real-time grammar correction, sentence-building exercises, and writing practice sessions that teach you to write naturally and correctly.

Common Grammar Mistakes That Lower IELTS Writing Scores

  1. Subject-Verb Agreement Errors

Mistake: He go to college every day.
Correction: He goes to college every day.
A mismatch between subject and verb is one of the most common reasons students lose marks. Remember: singular subjects take singular verbs, and plural subjects take plural verbs.

  1. Incorrect Tense Usage

Mistake: Yesterday I go to the library to study.
Correction: Yesterday I went to the library to study.
Inconsistency in tense confuses the examiner. Stick to one tense per sentence unless there’s a valid reason to switch.

  1. Misuse of Articles (a, an, the)

Mistake: She is best student in class.
Correction: She is the best student in the class.
Articles might seem small, but missing or misusing them changes meaning.

  1. Sentence Fragments and Run-ons

Mistake: Because he was tired. He slept early.
Correction: Because he was tired, he slept early.
Fragments are incomplete thoughts. Run-ons are overly long sentences without punctuation. Both reduce clarity.

  1. Punctuation and Comma Errors

Misplaced commas can change meaning entirely. For instance:
Let’s eat, Grandma! vs Let’s eat Grandma!
At ThinkEnglish, students practice punctuation through exercises that improve rhythm and flow in writing.

  1. Wrong Prepositions and Word Choice

Common mistakes: discuss about, dependent on of, married with.
Correct forms: discuss, dependent on, married to.

A strong foundation in grammar and vocabulary helps avoid these slips. That’s why ThinkEnglish IELTS coaching combines grammar learning with vocabulary enrichment activities.

How Grammar Impacts Coherence and Task Achievement

Grammar influences how smoothly your essay reads. Even great ideas can lose impact if the sentences are full of errors. Examiners look for accuracy, not just complexity.
For instance:

❌ The pollution is increase every year which is cause many diseases.
✅ Pollution is increasing every year, causing many diseases.

The corrected version is not only grammatically accurate but also concise and clear.

During ThinkEnglish’s IELTS coaching in Chandigarh, trainers guide you on sentence linking, transitions, and how to maintain logical flow without grammatical confusion.

Tips on How to Improve Grammar and Writing Skills for IELTS

Improving grammar doesn’t mean memorising rules — it means applying them through practice. Here’s how:

  1. Write every day. Even short paragraphs help. Focus on grammar accuracy before speed.

     

  2. Read model essays. Notice how grammar and sentence structure shape meaning.

     

  3. Take feedback seriously. Ask an expert or trainer to review your writing.

     

  4. Revise one grammar concept daily. Whether it’s tenses, articles, or prepositions, focus on one rule at a time.

     

At ThinkEnglish, trainers design grammar-based writing drills and provide individual feedback after every essay, ensuring constant progress.

How to Improve Grammar and Sentence Structure

Many students can write long essays but struggle with sentence construction. Good writing depends on variety — using simple, compound, and complex sentences correctly.

For example:
✅ People exercise regularly. (Simple)
✅ People exercise regularly because they want to stay healthy. (Complex)

ThinkEnglish helps students master sentence formation through guided writing practice, grammar correction sessions, and topic-specific writing tasks. By learning how to form balanced, clear sentences, you naturally improve your IELTS writing flow.

How to Improve Grammar and Vocabulary Together

Grammar builds structure, and vocabulary adds depth. You can’t score high without both.
Here’s what you can do:

  • Maintain a vocabulary notebook with new words and their sentence examples.

     

  • Practice collocations like “strong argument,” “heavy traffic,” “make progress.”

     

  • Learn the grammar that goes with each phrase (for example, depend on, interested in).

     

ThinkEnglish’s writing sessions combine grammar and vocabulary exercises, so students don’t just memorise words — they learn to use them correctly and contextually.
