Here's what examiners see dozens of times a day: essays where almost every sentence starts with "It is", "There are", or "In my opinion". This single habit can drop your score by half a band, sometimes more. You might have brilliant ideas and solid grammar, but if your sentences all sound the same, you're signalling weak sentence variety, which directly hits your Coherence & Cohesion score.
Let me be blunt. Repetitive sentence openings make you sound robotic. They hurt readability. They waste your chance to demonstrate control of English. And worst of all, they're completely fixable once you understand how examiners actually mark this.
The IELTS Writing band descriptors for Coherence & Cohesion explicitly mention "variety in sentence structures". Here's what bands 6, 7, and 8 expect:
Notice the language. Band 7 demands "variety of cohesive devices" AND "sentence structures". Band 8 goes further: "variety of cohesive devices AND sentence structures flexibly". If you're opening 60% of your sentences the same way, you're not hitting Band 7. Period.
Most students don't even realise they're doing this. You write, you check grammar, you move on. But you never actually sit down and count your sentence starters. That's where the blind spot lives.
Here's a quick diagnostic you can do right now. Take your last Task 2 essay. Highlight the first word of each sentence. Copy them all into a separate list. Now count duplicates. If any starter appears more than twice in a 280-word essay, you've got a problem. Ideally, you want mostly unique openers, or at least clear variety across your four paragraphs.
Quick Exercise: Run this check on three of your recent essays right now. Write down every sentence starter you use. Be honest about how many times "It is", "There are", and "I think" appear. This one exercise will shock you into change.
Let's work with an actual IELTS question: "Some people believe that technology has improved modern life, while others argue it has made life more complicated. Discuss both views and give your own opinion."
Weak: "There are many advantages to modern technology. There are several ways that technology improves productivity. There are also disadvantages that people often overlook. In my opinion, the benefits outweigh the drawbacks. In my opinion, education has become more accessible because of technology."
Count the starters: "There are" appears three times. "In my opinion" appears twice. This is lazy writing. Your argument sounds weaker than it actually is because the rhythm feels choppy and predictable.
Better: "Technology has transformed modern life in multiple ways. Some argue that automation boosts productivity and saves time. Others, however, contend that constant connectivity creates anxiety. From my perspective, the advantages clearly outweigh the disadvantages. Consider education, for instance: online platforms now reach students in remote areas."
See the difference? "Technology has", "Some argue", "Others, however", "From my perspective", "Consider education". Each opener does different grammatical work. The rhythm feels natural. Examiners subconsciously rate this higher because it demonstrates you can control your language.
Weak: "It is true that technology has changed communication. It is important to recognize both benefits and risks. It is clear that younger generations use technology more than older ones. It is undeniable that some jobs have been replaced by machines."
Four sentences. Four times "It is". This construction is grammatically safe, but safety isn't what Band 7+ demands. You're leaning on a crutch.
Better: "Technology has fundamentally reshaped how we communicate. Both benefits and risks deserve careful consideration. Younger generations use technology far more frequently than older populations. Job displacement through automation cannot be ignored."
Stronger? Yes. More direct? Absolutely. Why? You cut the weak construction entirely and let your content speak for itself. That's Band 7 territory.
Weak: "In conclusion, technology has positive and negative effects. In summary, people should use technology wisely. In brief, the future depends on how we manage this tool."
Your conclusion paragraph uses "In conclusion", "In summary", and "In brief" within three sentences. Overkill. And all three openings mean almost the same thing.
Better: "While technology undeniably brings problems, its advantages for healthcare, education, and communication far outweigh the risks. Rather than reject innovation, society must establish better safeguards and digital literacy programs. Ultimately, technology is neither good nor bad; our choices determine its impact."
Three sentences. Three completely different openers. Each one moves your argument forward. That's the gold standard.
Don't memorise these. Understand when to use each one.
In a 280-word essay, aim to use at least five different openers. In a 350-word essay, aim for seven or more. Repetition is what stops you from reaching Band 7.

Pro tip: After you've done this audit once or twice, you'll start noticing repetition while you write. Your brain will naturally reach for variety. That's when real improvement happens.
Mistake 1: Thinking variety means using complicated starters. You don't need every sentence to start with a participle phrase. You need consistency in avoiding the same starter twice in a row, and mixing up your approaches paragraph by paragraph.
Mistake 2: Starting the introduction and conclusion the same way. Many students write "In this essay, I will discuss..." and then "In conclusion, I have discussed...". This signals low sentence range. Your introduction and conclusion should feel different structurally.
Mistake 3: Mistaking synonyms for variety. "It is argued that" and "It can be said that" and "One could argue that" are still the "It is" structure at heart. Real variety changes the grammatical pattern, not just the words.
Mistake 4: Overusing questions. Rhetorical questions are powerful. One per essay maximum. Two or more feels forced and actually costs you points.
Let's be concrete. Imagine two essays on the same prompt, both with solid Task Response and Lexical Resource at Band 7 level.
Essay A: Uses the same five starters repeatedly. Coherence & Cohesion = Band 6. Final score = 6.5.
Essay B: Uses sentence variety strategically. Coherence & Cohesion = Band 7. Final score = 7.0.
That's a half-band difference. In most cases, that's the gap between a score you can use and a score you can't.
The IELTS scoring system averages across four criteria: Task Response, Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy. If you score 7, 6, 7, 7, your overall band is 6.75, which rounds to 7. But if you score 7, 5.5, 7, 7 (because of repetitive openings), you get 6.625, which rounds to 6.5. That's the difference between achieving your goal and falling short.
Beyond sentence starters, sentence structure itself plays a huge role in your Coherence & Cohesion score. If you're interested in deeper issues, our guide on sentence structure variety breaks down how to avoid monotonous patterns throughout your essay. You might also find it useful to check your repetitive phrases, which often work alongside repetitive starters to drag your score down.
Manually auditing sentence starters works, but it's tedious. An IELTS writing task 2 checker can scan your essay instantly and flag every repeated opener, showing you exactly where variety is weak. You'll see patterns you'd miss on your own, and get specific suggestions for rewrites.
The best IELTS essay checker tools don't just tell you "you used 'It is' three times". They show you the band score impact and suggest concrete alternatives using the techniques above. This saves time and makes your revision focused. Some also offer a band score calculator so you can see how corrections affect your overall result.
You know the problem. You know how to fix it. The only thing left is to do it.
Take one of your recent Task 2 essays and run the audit above. Spend 10 minutes rewriting sentences with repeated starters. Then read it aloud. You'll hear the difference immediately.
If you want faster feedback on this specific issue, use a free IELTS essay checker to get instant analysis of your sentence starters. You'll get actionable rewrites, not just criticism.
The students who move from Band 6 to Band 7 don't always improve their ideas. They improve their sentence control. Start there.
