You’ve practised your essays, you’ve learnt the vocabulary, but are you still stuck at Band 6.0 or 6.5? It’s incredibly frustrating, isn’t it?

In my experience as an IELTS tutor, I see talented students lose marks not because their English is poor, but because they fall into common traps. Writing Task 2 carries twice the marks of Task 1, so getting this right is crucial. Let’s look at the most frequent mistakes in Writing Task 2 and, more importantly, how to fix them.

1. The Trap of Not Answering the Whole Question

This is the number one reason candidates fail to reach Band 7.0 for Task Response. You might see a question that asks you to “Discuss both views and give your own opinion.”

If you only discuss the side you agree with, you haven’t answered the prompt. The examiner is looking for a balanced discussion. Make sure you underline the keywords in the question. If it asks for causes and solutions, don’t just list causes. You must cover every part of the prompt.

Sound familiar? It’s an easy mistake to make when you’re rushing.

2. Robotic Phrases and Memorised Templates

Examiners hate these. Phrases like “Since the dawn of time” or “It is a highly controversial issue” sound unnatural and forced. They don’t show your ability; they show you can memorise a script.

Instead of overusing clichéd phrases, try to use natural collocations. Write as if you are discussing a serious topic with a colleague, not reciting a poem. Be clear, be direct, and be yourself.

3. Paragraphing Problems

Imagine reading a book with no chapters or breaks. It would be a nightmare, right? The same goes for your essay.

Some students write one giant block of text, while others write ten tiny sentences as separate paragraphs. Neither is good. You need a clear structure:

• Introduction
• Body Paragraph 1 (One main idea)
• Body Paragraph 2 (Another main idea)
• Conclusion

Each body paragraph should start with a topic sentence that tells the reader what the paragraph is about. Keep it organised.

4. Informal Language in Academic Writing

IELTS Academic is… well, academic. This means no slang and no contractions.

• Don’t write: “I can’t believe…”
• Do write: “I cannot accept…”
• Don’t write: “Kids these days…”
• Do write: “Children today…”

Keep your tone formal and professional. Save the casual chat for your friends or the Speaking test (where it’s slightly more acceptable, but still, be careful!).

5. Using Big Words Wrongly

We all want to impress the examiner with fancy vocabulary. But using a complex word incorrectly is worse than using a simple word correctly.

For example, don’t use “commence” when you mean “start” unless it fits the context perfectly. Don’t say “elucidate” if “explain” works better. Clarity is king. If the examiner has to guess what you mean, you lose marks.

6. Not Having a Clear Position

For opinion essays, the examiner needs to know what you think. And they need to know it from the start.

Don’t wait until the very last sentence to reveal your opinion like it’s a mystery novel twist. State your position in the introduction, support it throughout the body paragraphs, and restate it in the conclusion. Consistency is key to a high score in Coherence and Cohesion.

7. Repeating Ideas and Vocabulary

If you use the word “important” ten times in your essay, it shows a limited vocabulary. Try to use synonyms like “significant,” “crucial,” or “vital”—but only if you are sure they mean the same thing in that context.

Also, don’t just repeat the same argument in different words. Develop your ideas. Give examples. Explain why something is true.

Conclusion

Avoiding these common mistakes is half the battle. You don’t need to be Shakespeare to get a Band 7.0 or higher; you just need to be clear, structured, and relevant.

Take some time to review your practice essays. Do you see any of these errors? If so, don’t worry—identifying them is the first step to fixing them. You’ve got this!
