Most candidates repeat the same Task 1 mistakes that examiners see hundreds of times per week. These errors directly cause band score ceilings of 5 or 6, preventing otherwise capable writers from reaching Band 7. This guide identifies the 10 most costly Task 1 mistakes and gives specific, actionable fixes for each one.
1Mistakes 1–3: Structure and Overview Errors
Mistake 1: No overview paragraph. The overview is explicitly required by the Band 7 descriptor. Fix: Always write an overview as your second paragraph. Mistake 2: Copying the question prompt word for word. The introduction must be paraphrased. Fix: Change at least 3–4 words in the topic sentence — use synonyms, change word order, change sentence structure. Mistake 3: Putting data in the overview. The overview should contain only trends and patterns, never specific numbers. Fix: Check your overview sentence — if it contains any number, delete it and move it to a body paragraph.
2Mistakes 4–6: Data Handling Errors
Mistake 4: Reporting every data point. A Band 5 response lists all data sequentially; a Band 7 response selects and compares. Fix: Before writing, circle only the 6–8 most important data points and ignore the rest. Mistake 5: No grouping. Candidates describe each data series one by one without comparing them. Fix: In your body paragraphs, always pair or contrast at least two items in each sentence. Mistake 6: Ignoring exceptions and anomalies. Missing the one country that went against the overall trend shows analytical weakness. Fix: After identifying the main trend, scan specifically for anomalies — they are often the examiner's intended second feature.
3Mistakes 7–8: Language Errors
Mistake 7: Using only two or three trend words throughout the entire response. Writing 'increased' and 'decreased' in every sentence severely limits Lexical Resource. Fix: Prepare and memorise 5 upward and 5 downward trend verbs before the exam and use at least 4 different ones in each response. Mistake 8: Incorrect prepositions with data. Common errors: 'increased to 20% from 15%' (should be: 'increased from 15% to 20%'), 'rose by 2015' (should be: 'rose until 2015' or 'had risen by 2015'). Fix: Practise: rose FROM X TO Y, increased BY X (amount of change), reached a peak IN (year), fell OVER the period.
4Mistakes 9–10: Process and Timing Errors
Mistake 9: Adding personal opinion or explanation. Task 1 asks you to report data, not interpret why it happened. Writing 'this is probably because of globalisation' or 'the government should address this' is off-task and reduces Task Achievement. Fix: Only describe what the data shows. Never write 'I think' or 'this might be because'. Mistake 10: Under or over-writing on word count. Under 150 words is automatically penalised. Over 250 words wastes time needed for Task 2, which is worth twice as much. Fix: Aim for 165–185 words. Count your practice responses until you have a reliable sense of your natural word count.
🎯 Key Takeaway
Every one of these mistakes is correctable with targeted practice. Pick the two or three errors most relevant to your writing, practise fixing them in isolation, and test yourself by reviewing a recent practice response before attempting the next. Systematic mistake elimination is the fastest route to Band 7 in Task 1.
