You're sitting in the exam. Your pen is moving. You feel confident about your essay. Then, weeks later, you get your results: Band 6.5 instead of the 7.5 you needed.
What went wrong?
Here's the thing: most band score drops aren't about bad ideas or weak arguments. They're about small, preventable errors that pile up across your essay and tank your Grammatical Range & Accuracy or Coherence & Cohesion scores. I've graded hundreds of essays, and the IELTS writing mistakes are almost always the same ones.
The good news? Once you know what they are, you can fix them.
IELTS Writing demands formal, academic tone. Not stuffy. Not robotic. Just professional.
But here's what happens: students slip into conversational English without realizing it. They write "get", "a lot of", "kids", "stuff"—the words they use every day. Then they lose Lexical Resource points because the examiner expects range and precision in word choice.
Weak: "Lots of kids get problems from social media, and it's a real issue these days."
Better: "Numerous adolescents experience psychological difficulties stemming from excessive social media use, constituting a significant contemporary challenge."
Notice the second version uses academic vocabulary (numerous, stemming from, constituting), maintains distance, and reads like something you'd find in a textbook. That's what IELTS rewards. You don't need to sound artificial—just professional.
Read this paragraph out loud: "The government should invest in education. The benefits are significant. The long-term outcomes improve. The economy grows as a result."
Every sentence starts with "The". Your essay becomes monotonous, and that hurts Coherence & Cohesion. Examiners specifically look for syntactic variety—different sentence structures, different opening words, deliberate variation in how you construct ideas.
Weak: "The government should invest in education. The benefits are significant. The long-term outcomes improve. The economy grows as a result."
Better: "Investing in education yields substantial long-term benefits. Not only does this strengthen the economy, but it also reduces inequality across generations. Moreover, societies that prioritize educational funding consistently outperform those that don't."
The second version opens with a verb (Investing), then shifts to a different structure (Not only does), then uses a dependent clause. This shows you can manipulate English syntax deliberately, which Band 7 and above scorers must demonstrate.
Quick fix: Count how many sentences start with "The" in each paragraph. If it's more than one, rewrite one using a different opener: an adverbial clause (Although..., When...), a verb phrase (Investing..., Creating...), or a prepositional phrase (With recent advances..., Throughout history...).
Many students treat linking words like magic Band 7 dust. Throw them everywhere and score higher, right?
Wrong. Misused linking words damage your score. If you use "however" when you mean "and", or "therefore" when there's no logical consequence, examiners notice immediately. That's a Coherence & Cohesion penalty.
Weak: "Some people believe remote work is beneficial. Therefore, climate change is a serious problem."
Better: "Some people believe remote work is beneficial because it reduces commuting. Consequently, this decreases carbon emissions and mitigates climate change."
The second version uses "Consequently" because there's actual logical support. The ideas connect. That's the difference between fluent cohesion and forced linking.
Real talk: Before you use a linking word, ask yourself out loud: "Does this idea actually follow from the previous sentence?" If not, delete it. Fewer, correctly-placed linking words score higher than many misused ones. Quality beats quantity every time.
Task Response is 25% of your Writing score. That's a quarter of your grade.
Yet many students meander through their essays without ever stating a clear position. You might write a thoughtful response about remote work benefits and drawbacks, but if the question asks "Do you think remote work is beneficial?", you need to pick a side or explain your nuanced stance explicitly. IELTS doesn't reward fence-sitting without clarity.
Weak: "Remote work has advantages and disadvantages. Some people prefer working from home while others like offices. Both options are valid."
Better: "While remote work offers flexibility and reduced commuting time, I believe that collaborative, in-office environments ultimately produce better outcomes for most organizations, particularly in creative and mentorship-dependent roles."
The second response commits to a position while acknowledging counterarguments. This shows you understand the question and can argue persuasively, which is exactly what Band 7 Task Response requires.

You don't need flawless grammar to hit Band 7. But you do need to demonstrate control over basic structures and avoid errors that distract the examiner.
The most expensive mistakes are articles (a/an/the), tense consistency, and subject-verb agreement. These are foundational. Errors here tell the examiner you either didn't proofread or don't have solid grammar knowledge.
Weak: "The educations in many countries is poor. Students doesn't have access to resources, and it make learning difficult."
Better: "Educational systems in many countries are inadequate. Students lack access to resources, and this makes learning difficult."
In the weak version: "educations" (education is uncountable), "is" with a plural subject, "doesn't" with plural noun, "make" instead of "makes". These pile up fast and hurt your Grammatical Range & Accuracy score.
Time-saving tip: Spend your last 3-5 minutes reading your essay aloud, checking only for articles, tense consistency, and subject-verb agreement. Don't try to rewrite everything. Just fix these three high-impact areas.
Task 2 questions often have multiple parts. A typical question might ask: "What problems does this create? What solutions can you suggest?"
If you ignore one part, you're automatically capped at Band 6 for Task Response. The IELTS band descriptors are explicit: you must "fully" address all parts of the prompt.
Here's what you do: read the question twice. Underline every instruction. Count how many things you need to discuss. Then make sure your essay covers each one, ideally in separate paragraphs. For complex multi-part questions, check our discussion essay guide and problem-solution framework.
Before you write: Spend 30 seconds writing a mini-outline. Label each part of the question. Write which paragraph will address it. This prevents you from forgetting an instruction mid-essay.
IELTS assesses Lexical Resource, which means your ability to use a range of vocabulary accurately. Repeating the same words shows limited range.
If you write "technology is important" in Paragraph 1, "technology plays an important role" in Paragraph 2, and "the importance of technology" in Paragraph 3, you're not demonstrating vocabulary range. You're drilling the same idea.
Weak: "Smartphones affect young people. Mobile phones change how young people communicate. These devices impact the social skills of young people."
Better: "Smartphones fundamentally alter how adolescents interact. These portable devices reshape communication patterns, diminishing face-to-face dialogue. Such technological reliance has profound implications for social development."
The second version uses different vocabulary (alter, reshape, dialogue, reliance, implications) while discussing the same concept. This shows lexical variety, which Band 7 and above scorers must demonstrate. Our paraphrasing guide gives you specific techniques for saying the same thing different ways.
Editing trick: After your first draft, highlight all instances of your most-used word (probably "important", "people", "problem", or "develop"). Replace at least half with synonyms or paraphrases.
Task 1 requires a minimum of 150 words. Task 2 requires 250 words. But if you write 450 words for Task 1 by repeating ideas or adding fluff, you're wasting time and making more mistakes per word, which lowers your overall score.
Longer doesn't mean better. Clearer, more concise, and more varied does. Aim for Task 1: 160-190 words. Task 2: 280-320 words. Stay efficient. Every sentence should earn its place.
Practical approach: If your first draft is over 350 words for Task 2, read it once and delete any sentence that doesn't add new information or strengthen your argument. Cut ruthlessly.
Task 1 isn't just description. It's data interpretation.
Yet many students simply list what they see in a chart or graph without analyzing trends, making comparisons, or highlighting key patterns. If you write "In 2020, 45% of people used email. In 2021, 50% used email", you're just reading numbers. You're not analyzing.
Task 1 requires you to "present the main features" and make "comparisons where relevant". That means grouping data meaningfully and identifying trends.
Weak: "The graph shows data from 2010 to 2020. In 2010, the figure was 30%. In 2015, it was 50%. In 2020, it was 70%."
Better: "Over the decade from 2010 to 2020, the figure more than doubled, rising from 30% to 70%. This sharp acceleration, particularly pronounced between 2015 and 2020, indicates a dramatic shift in consumer behavior."
The second version groups data meaningfully, identifies trends (acceleration), and interprets significance (dramatic shift). This satisfies both Task Response and Coherence & Cohesion requirements.
You have 60 minutes total for both tasks. Many students spend 50 minutes writing and 10 minutes panicking. That leaves zero time to proofread, so preventable errors slide through.
Spelling mistakes and punctuation errors get marked in Grammatical Range & Accuracy, and they lower your score. A single misspelled word might not hurt much, but five or six across both tasks add up.
