The 5 IELTS Writing Mistakes That Are Quietly Lowering Your Band Score

Most IELTS Writing candidates make the same five mistakes. Not the mistakes they think they make. Not the mistakes their AI tool flags. A different five, the ones that examiners see across almost every submission, from Task 2 essays to GT letters to chart analyses. And most candidates make all five without realising.

Here they are, with the fix for each.

1. Repeating the prompt instead of paraphrasing it.
The prompt says "Some people believe that working from home is better." The candidate writes "Some people believe that working from home is better" and adds "In this essay I will discuss this topic." That's not paraphrasing. That's copying with a follow-up. Real paraphrasing changes both structure and vocabulary. If your introduction shares more than a couple of content words with the original prompt, rewrite it.

2. Stating examples instead of using them as evidence.
"Working from home saves time. For example, many employees work from home." This isn't an example. It's a restatement of the claim. A real example is specific enough to prove the point. Compare: "A software developer based in Manchester can begin work at six in the morning to overlap with colleagues in Singapore, reclaiming the afternoon for family time." That does actual work. The generic version doesn't.

3. Missing or misplacing a bullet point in GT letters.
Every GT Task 1 letter has three bullet points. Mentioning a bullet in passing isn't the same as developing it. If the bullet says "describe what happened," you need at least one supporting detail beyond "the delivery was late." Missing a bullet costs half a band. Developing each one lifts your Task Achievement from Band 5 to Band 7.

4. No overview in chart analyses.
Academic Task 1 has a hard rule. Without an overview, your score is capped at Band 5. An overview isn't a list of data points. It identifies the main trend or pattern across the chart. If the chart shows smartphone ownership rising across all age groups from 2005 to 2025, your overview names that trend. Listing individual percentages is not an overview.

5. Stacking basic linkers at the start of every sentence.
"Firstly, public transport reduces traffic. Moreover, it lowers pollution. Furthermore, it is cheaper." Four sentences, four linkers, all at the start. That's not Band 7 cohesion. It's a checklist. Band 7 uses fewer linkers, placed inside sentences, doing real connective work. Compare: "Public transport not only reduces urban traffic and lowers air pollution but also offers a cheaper alternative to driving." One sentence, one linker, real connection between the ideas.

These five mistakes appear across all three task types. Fix them and your Band 6 becomes a Band 7, without learning new vocabulary or writing longer sentences.

What Band Score Are You Really At? Three Ways to Self-Assess Honestly

Most IELTS candidates have no idea what band score they're actually writing or speaking at.

That might sound harsh, but it isn't. It's just that without a trained eye scoring your work against the four criteria, you're either overestimating (because the essay "looks good") or underestimating (because you're nervous). Both cost you the same thing - time spent preparing for the wrong band.

Here's are three ways you can self-assess from now on without an examiner present.

1. Score yourself by criterion, not by impression.
The most common self-assessment mistake is reading your own essay and asking "is this good?" That gives you a vague answer. Instead, score each criterion separately. For Writing: Task Response, Coherence and Cohesion, Lexical Resource, Grammatical Range and Accuracy. For Speaking: Fluency and Coherence, Lexical Resource, Grammatical Range and Accuracy, Pronunciation. Your weakest score sets your overall band, not your strongest. So if you're a Band 7 on three criteria but a Band 5 on one, your overall is Band 6 - not Band 6.5, not "almost 7." Band 6.

2. Compare against real samples - not aspirational ones.
Looking at Band 9 samples is useful for direction. But to grade yourself accurately, you need Band 5, 6, and 7 samples side by side. The gap between your work and Band 7 is rarely what you think it is. It's not vocabulary. It's not grammar. It's usually one specific thing - like covering the prompt but failing to develop a position, or using simple words instead of precise ones.

3. Get one piece of work properly scored - and keep that calibration.
You only need one essay to be graded by an examiner. Once you know honestly what your Band 6 looks like, you can self-assess everything that follows from that benchmark.

The point of self-assessment isn't to give yourself a number. It's to know which criterion is holding you back so you stop preparing for the wrong thing.
