I had a webinar attendee last month—let's call him Marco—who was absolutely convinced the IELTS examiners hated him.
He had memorized lists of high-level vocabulary. He knew exactly how to structure a four-paragraph essay. When he handed me his practice essays, they were packed with words like ubiquitous and detrimental. He felt certain he was writing at a Band 7.5 level.
Then his official results came back. Grammatical Range and Accuracy: 6.0.
Marco was furious. "But I used complex sentences!" he told me. "I used nevertheless and notwithstanding!"
He wasn't wrong. He did use them. The problem was that he used them incorrectly, and in the process of trying to sound like a university professor, he completely destroyed the readability of his essay.
This is probably the most common trap I see students fall into when trying to boost their writing score. They assume the examiner wants to read Shakespeare. They don't. What examiners actually want—what they are trained to look for—is precision. Control. The ability to communicate an idea without making the reader stumble over the words.
If you're stuck at a 6.0 in writing, it's rarely a lack of ideas holding you back. It's almost always because you're making fundamental errors you don't even notice, or you're forcing complicated grammar that just doesn't fit.
Let's break down what the examiner is actually grading, and how you can fix your score without having to memorize another grammar textbook.
Your grammar score makes up exactly 25% of your total writing grade. The examiners are looking at two very specific things here: Range (the variety of your sentences) and Accuracy (how many mistakes you make) (1).
| The Criteria | What It Means in Plain English | How to Actually Get the Points |
| Range | Do you only write short, simple sentences? | You need to show you can write simple, compound, and complex sentences naturally. |
| Accuracy | How often do you mess up? | A Band 7 requires "frequent error-free sentences." If every sentence has a tiny mistake, you're stuck at a 6.0. |
| Punctuation | Are your commas doing their job? | Don't write run-on sentences. Make sure your clauses are separated properly. |
| Communicative Effect | Do your mistakes confuse the reader? | If the examiner has to read your sentence twice to understand it, your score drops. Fast. |
Look closely at the official Band 7 descriptors. To get that score, you need to use "a variety of complex structures" and produce "frequent error-free sentences" (2).
Notice what's missing? It doesn't say "perfect grammar." You are allowed to make a few mistakes. But the vast majority of your sentences need to be completely clean.
There's this weird myth floating around IELTS forums that every single sentence in your essay needs to be incredibly long and complicated. It's terrible advice. When you try to write a 45-word sentence with three different clauses, your chances of making a grammatical error go through the roof.
Instead, I like to preach about the 50/50 Rule.
Roughly half of your sentences should be clear, accurate, simple, or compound sentences. The other half should be well-controlled complex sentences.
What's a complex sentence? It's just an independent clause (a complete thought) joined with a dependent clause (an incomplete thought) using words like although, because, while, if, or which (3). That's it. It doesn't need to be a paragraph long.
When you balance simple clarity with controlled complexity, you show the examiner you have range, but you don't sacrifice your accuracy to do it.
Let me show you exactly how trying too hard ruins an essay.
Imagine you're writing about whether governments should tax sugary drinks.
The "Before" Example (Band 5.5 - 6.0)
"Although many people are consuming too much sugar every day, but as a result they are developing health problems, even though a tax would help them stop which is good for society."
Why this fails: This student is desperately trying to show off their range by cramming although, but, even though, and which into a single breath. It's a mess. You can't use "although" and "but" in the same sentence. It's a massive run-on that completely loses its point. The examiner will penalize this heavily.
The "After" Example (Band 7.0+)
"Many people consume excessive amounts of sugar daily, and as a result, they often develop serious health issues. Although a sugar tax might be unpopular, it would effectively discourage this habit and benefit society as a whole."
Why this works: This is what a Band 7 actually looks like. The chaotic thought has been broken into two distinct sentences. The first is a clean compound sentence. The second is a perfectly executed complex sentence using "although." It's precise. It's easy to read. It's error-free.
You can't learn all of English grammar in a week, but you can eliminate the most common score-killing mistakes right now.
1. Fix your subject-verb agreement.
This is the number one error I see, even from advanced students. If your subject is singular, your verb has to be singular. Writing "The number of cars are increasing" instead of "is increasing" instantly tells the examiner you lack basic control (3).
2. Stop guessing with your articles.
Knowing when to use "a," "an," or "the" isn't optional. Remember that "the" is for specific items or when there's only one of something (the environment, the government). Don't use "the" when talking about plural nouns in a general sense. Write "Computers have changed society," not "The computers have changed society" (4).
3. Actually proofread your punctuation.
A missing comma can change the entire meaning of a sentence. Make sure you're using commas correctly after introductory linking words (like "Furthermore, the government should...") and when you're separating clauses (4).
Before you finish your next practice essay, ask yourself these questions:
• Did I use a mix of simple, compound, and complex sentences, or do they all look the same?
• Did I check every single sentence for basic subject-verb agreement?
• Are my articles (a, an, the) actually doing what they're supposed to do?
• Did I accidentally write any massive, confusing run-on sentences?
• Did I leave myself 3 minutes at the end just to proofread?
Getting a high grammar score isn't about showing off. It's about control. Stop trying to write convoluted sentences that lead to mistakes, and start focusing on clear, accurate structures that actually communicate your ideas.
If you're tired of guessing whether your sentences are correct, my IELTS General Writing Prep Course breaks down exactly how to build these structures flawlessly. I cover complex sentences, relative clauses, and I provide the specific, detailed feedback you need to walk into that exam room knowing exactly what you're doing.
March 30, 2026
You spent three weeks staring at flashcards. You walked into the exam room, saw a prompt about the environment, and practically vibrated with excitement because you finally got to use "plethora" and "ubiquitous" in the same paragraph. You walked out feeling like an absolute genius.
Then the results dropped. Lexical Resource: 6.0.
What on earth happened?
I see this exact scenario play out constantly. Students think the examiner is sitting there with a checklist of obscure 19th-century vocabulary, just waiting to hand out Band 7s to anyone who sounds like a walking thesaurus. But that isn't how it works. At all. Forcing massive words into sentences where they don't belong is actually the fastest way to tank your score.
When an examiner grades your essay for Lexical Resource, they are looking at four specific things (1):
| What Examiners Look For | What It Actually Means | How to Get the Points |
| Range | Do you use a variety of words? | Avoid repeating the exact same words from the prompt over and over. |
| Accuracy |
Are you using the word correctly? |
Don't use a word unless you are 100% sure of its meaning and context. |
| Natural Usage | Does it sound like a native speaker? | Focus on collocations (words that naturally go together) rather than isolated "big" words. |
| Spelling & Word Formation |
Did you spell it right? |
Double-check your work. Using "affect" instead of "effect" costs you points. |
Notice that "uses words nobody has heard since 1850" is not on that list. To hit a Band 7 or higher, you need to show flexible and precise use of language, not just a list of memorized synonyms (2).
If memorizing lists of "Band 9 words" is a waste of time, what are you supposed to do?
Collocations.
It is a fancy grammar term for a very simple concept: words that naturally go together. Native speakers don't just combine words randomly. They say "heavy rain." If you say "strong rain," I know exactly what you mean, but it sounds slightly off. They "make a decision," they don't "do a decision."
When you use natural collocations, your writing instantly feels sophisticated (3). You don't need bizarre vocabulary if your simple words are paired perfectly.
Let me show you how trying too hard actually ruins a sentence.
The Context: You are writing an essay about the environment and want to say that pollution is a big problem.
"Air pollution is a ubiquitous conundrum that makes a plethora of bad effects on the globe."
What's the issue here: This student is trying so hard it hurts. "Ubiquitous conundrum" sounds ridiculous. "Plethora" is the ultimate memorized IELTS word—it almost never fits the tone of an academic essay. And "makes bad effects"? That is an incorrect collocation. We don't "make" effects, we "have" them . The examiner takes one look at this and knows you memorized a list.
"Air pollution is a pressing issue that has a severe impact on the global environment."
Why it works: There are no weird, outdated words here. Just highly accurate, natural collocations: "pressing issue" and "severe impact." It sounds effortless. It sounds precise. This is what a Band 7 actually looks like.
Upgrading your vocabulary doesn't happen overnight, but you can stop making the big mistakes right now.
First, step away from the thesaurus. If you look up a synonym, do not put it in your essay unless you have seen it used in a real sentence . Words have subtle vibes and tones that a dictionary won't tell you.
Second, when you paraphrase the prompt in your introduction, don't go crazy. You don't have to change every single word . If you change too much, the sentence stops making sense. Keep a few key terms if there isn't a perfect synonym.
And honestly? When in doubt, just keep it simple. If you are debating between a simple word you know how to use perfectly and a complex word you are only 70% sure about, pick the simple one. Every single time. Accuracy beats complexity.
Before you call your next practice essay done, ask yourself:
[ ] Did I paraphrase naturally, or did I butcher the meaning?
[ ] Am I repeating the same nouns in every paragraph?
[ ] Did I force any "advanced" words that feel a bit clunky?
Mastering vocabulary is about precision. Stop trying to sound like a dictionary, and start focusing on clear, natural phrasing.
