You're Not Bad at English.
You're Bad at IELTS.
Read this before you write a single practice essay
You have full conversations in English. You watch films without subtitles. Your colleagues never suspect you are not a native speaker. And then your IELTS result arrives, band 6.0, and it feels like a slap. Here is the truth nobody tells you at the start: IELTS is not an English test. It is a format test. And once you understand that distinction, everything changes.
“IELTS is not testing whether you can speak English. It is testing whether you can perform English in a very specific way.”
What the examiner is actually marking
When a Writing examiner reads your essay, they are not thinking about whether you speak good English. They are running through four criteria, each worth 25% of your score. Miss any one of them and your band drops, no matter how beautiful your vocabulary is.
Task Achievement (or Task Response for Task 2)
Did you actually answer the question? All of it? Many candidates write brilliant essays about the wrong thing. They address part of the prompt, miss a key instruction, or spend 250 words on one side and two sentences on the other. The examiner notices immediately.
Coherence and Cohesion
Does your essay flow logically? Each paragraph should have one clear central idea. Your sentences should connect to each other. Using Furthermore and However everywhere does not create cohesion, it creates noise. Real cohesion is when a reader never loses the thread of your argument.
Lexical Resource
This is about range, precision, and control of vocabulary. Using the same word three times in a paragraph hurts your score. So does using a word you half-know in the wrong context. Examiners reward candidates who use a smaller set of words accurately over those who use complex words hopefully.
Grammatical Range and Accuracy
Simple sentences written perfectly will outscore complex sentences written badly. Every time. A mix of sentence types, short punchy statements alongside longer subordinate-clause constructions, shows range. Errors that confuse meaning damage your score the most.
The three mistakes fluent speakers make most
Mistake 1: Writing how you think, not how the examiner marks
Fluent speakers often write naturally and expressively. IELTS Task 2 wants a structured academic argument with a clear position, supported body paragraphs, and a conclusion that mirrors the introduction. If you write like a journalist or a conversationalist, you are losing points even if every sentence is perfect.
Mistake 2: Treating word count as the finish line
Getting to 250 words and stopping is not a strategy. Examiners can spot padding from the first sentence. Phrases like It goes without saying that or As we all know in today's modern society add zero marks and signal a weak introduction. Every sentence should earn its place.
Mistake 3: Ignoring the Task Achievement criterion completely
This is the silent score-killer. A candidate writes a well-structured, grammatically clean essay but gives a one-sided argument when the question asked them to discuss both views. Task Achievement is marked first for a reason.
“The band 7 student is not smarter than the band 5.5 student. They just know what the examiner is looking for and they give it to them.”
What actually moves the needle
Quick wins worth practising this week
- Read the question twice and identify exactly what it is asking before you write a single word
- Write a one-sentence thesis statement for every Task 2 essay. If you cannot summarise your position in one sentence, it is not clear enough
- Ban filler openers: never start an essay with Nowadays or In today's world
- Use 3 different sentence structures per paragraph, a simple statement, a complex sentence, and a relative clause
- Reread your conclusion and your introduction side by side. If they do not clearly match, rewrite one of them
The honest truth
Getting to band 7 in Writing is not about studying harder. It is about studying the right thing. Most candidates who are stuck at 6 or 6.5 are practising the wrong skill. They are writing more essays instead of understanding why their current essays are losing marks.
Spend one week reading the band descriptors out loud. Read a band 7 sample essay and ask yourself, for each paragraph, which criterion does this sentence serve? Do that exercise five times and you will understand more about IELTS Writing than most candidates learn in a year of classes.
The single most important shift
Stop thinking like a writer. Start thinking like an examiner. Before you submit any practice essay, score it yourself against all four criteria. That moment of self-assessment, uncomfortable as it is, is where real improvement lives.
