Many candidates lose marks in Task 1 not because they lack ideas, but because they repeat the same small mistakes. These errors usually come from habits that feel natural in everyday writing but are penalised in IELTS. The good news is that most of them are straightforward to correct once you recognise them.
Here are seven of the most common mistakes — with clear examples and practical fixes.
Writing too few words
The minimum is 150 words, but many candidates stop at 130–140 because they run out of time or ideas. Under-length responses are penalised in Task Achievement — even if everything else is accurate.
Fix: Always aim for 160–180 words. Spend the last minute counting. If you are short, add one more detail to the overview or extend a comparison sentence. Practise writing full responses in 18 minutes so the length becomes natural.
Forgetting the overview
The overview is the most important sentence in Task 1. It gives the examiner a clear summary of the main trends or stages. Without it, you cannot score higher than Band 5 for Task Achievement, even if every detail is correct.
Fix: Always write one or two sentences after the introduction that summarise the biggest patterns. Do this before you write any details — it keeps your answer focused and shows clear understanding.
Copying words from the question
The examiner expects you to paraphrase the title and labels. Copying phrases like "the graph shows" or "the number of people" lowers your Lexical Resource score.
Fix: Train yourself to change vocabulary immediately. Examples:
Write the introduction in your own words before looking at the data.
Including too much detail
Listing every single number or point wastes time and makes the answer difficult to follow. The examiner wants key features, not a full list.
Fix: Choose only 2–3 main trends per paragraph. Group similar data (e.g., "Sales for all three products rose steadily, peaking in 2020"). Ignore small changes unless they are significant (e.g., a sudden drop or crossover).
Writing in the wrong style
Task 1 is formal academic writing. Candidates often use contractions ("it's", "don't"), informal words ("a lot of", "really high"), or personal opinions ("I think"). These lower both Grammatical Range and Lexical Resource scores.
Fix: Use full forms and neutral language: "it is" instead of "it's", "a significant increase" instead of "really high". Never include "I think" or "in my opinion" — Task 1 has no opinion.
Poor organisation and linking
Some answers jump between ideas without clear connections, or repeat the same linking words ("also", "and", "then"). This affects Coherence and Cohesion.
Fix: Use a small set of precise linkers:
Plan two body paragraphs: one for main trends, one for comparisons or exceptions.
Spelling and word-formation errors
Misspelling common words ("goverment", "enviroment") or using the wrong word form ("increase" instead of "increased") costs marks in Lexical Resource and Grammatical Range.
Fix: Learn the most frequent IELTS words and their forms (noun/verb/adjective). Always leave 1–2 minutes to check spelling — especially numbers, units (million/%), and topic vocabulary (e.g., "consumption", "production").
Final tip
Practice one full Task 1 every day for two weeks using the fixes above. Record your word count and overview sentence. Most candidates see a 0.5–1.0 band improvement simply by avoiding these seven mistakes.
