That single fact changes everything about how you should approach it. A weak essay does not just pull down your Writing band — because your overall band score is the mean of all four skills, a low Writing score drags your final number down harder than most candidates realise. The four marking criteria for Task 2 are **Task Response**, **Coherence & Cohesion**, **Lexical Resource**, and **Grammatical Range & Accuracy** — each weighted equally at 25%. So a beautiful vocabulary score cannot rescue a structurally incoherent essay. You need all four cylinders firing. Below I break down the mistakes I see most consistently in Task 2 — not as a vague list, but with the *why* behind each one, so you can actually fix them. --- ## Mistake 1 — Misreading the Question and Drifting Off-Topic This is the single most damaging error, and it feeds directly into Task Response — the criterion that asks: *did you actually answer what was asked?* IELTS Task 2 questions come in several distinct types: **opinion essays** ("To what extent do you agree or disagree?"), **discussion essays** ("Discuss both views and give your opinion"), **problem-solution essays**, and **advantage-disadvantage essays**. Each demands a different structure. Treating a discussion essay as a pure opinion essay — or ignoring the instruction to give *your* opinion — will cap your Task Response score at Band 5, no matter how fluent your English is. The fix is deceptively simple: underline the **task instruction verb** and the **topic focus** before you write a single word. Then check your thesis sentence directly answers both. > The essay question asks: *"Some people believe that governments should fund arts programmes. Others think this money should go to public services. Discuss both views and give your own opinion."* > A strong thesis: **"While arts funding enriches cultural life, I believe essential public services should take priority in government budgets."** Notice that this thesis does three things: acknowledges both sides, signals the essay structure, and commits to a clear position. That is Task Response in one sentence. --- ## Mistake 2 — A Thesis Statement That Says Nothing Related to the above but distinct: many candidates write an introduction that paraphrases the question and then adds a non-committal closer like *"This essay will discuss the advantages and disadvantages."* That is not a thesis — it is a table of contents, and it scores poorly on Task Response because the examiner cannot see your position. A thesis must **commit**. You do not need to be extreme, but you must be clear. Examiners are trained to reward a well-supported argument, not a safe, opinion-free summary. > Weak thesis: **"There are many arguments both for and against the use of social media by young people."** > Strong thesis: **"Although social media offers young people genuine opportunities for connection and learning, the risks to mental health outweigh these benefits and warrant tighter parental controls."** The second version tells the examiner exactly where the essay is going. That clarity earns marks from the very first paragraph. --- ## Mistake 3 — Underdeveloped Body Paragraphs A common pattern: candidates state a point, add one thin example, and move on. Two body paragraphs of four sentences each will not get you to Band 7. Examiners want to see **extended and supported ideas** — that phrase appears verbatim in the Band 7 Task Response descriptor. The most reliable paragraph structure is **Point → Explanation → Example → Link back**. The explanation step is where most marks are lost. Saying "Social media is harmful" is a point. Explaining *why* — because constant comparison with curated content triggers anxiety in developing adolescents — is development. That is what separates a Band 6 paragraph from a Band 7 one. Aim for roughly 90–120 words per body paragraph. That gives you enough room to develop without padding. --- ## Mistake 4 — Overusing Transition Words as a Crutch Coherence & Cohesion does not mean starting every sentence with *Furthermore*, *Moreover*, or *In addition*. That is one of the most widespread misconceptions I see, and it actively hurts your score. The Band 7 descriptor for Cohesion specifically warns against **"mechanical"** use of cohesive devices. True cohesion is about **logical flow** — the reader should be able to follow your argument without needing a signpost on every sentence. Use pronouns, synonyms, and sentence structure to link ideas, not just connectors. > Mechanical (penalised): **"Social media is popular. Furthermore, it is used by many people. Moreover, young people use it every day. In addition, it affects mental health."** > Coherent: **"Social media has become embedded in daily life, particularly among younger generations — and this ubiquity is precisely what makes its psychological effects so difficult to ignore."** The second version uses a dash and a pronoun (*this ubiquity*) to connect ideas. It reads like a real argument, not a list. --- ## Mistake 5 — Vocabulary That Looks Advanced but Isn't Accurate Lexical Resource rewards **precision and range**, not just complexity. A very common error is reaching for an impressive-sounding word without checking its meaning or collocation. This often produces sentences that are technically grammatical but semantically odd — and examiners notice immediately. For example, *"mitigate"* does not collocate with *"problems"* the way candidates think. You mitigate *risks* or *effects*, not problems directly. Similarly, *"detrimental"* is almost always followed by *"to"*, not *"for"*. > Incorrect collocation: **"The government should mitigate the problems of unemployment."** > Correct collocation: **"The government should implement policies to mitigate the effects of unemployment."** The practical fix: when you learn a new word for essay writing, learn it *in a phrase*, not in isolation. Learn *"pose a significant threat to"*, not just *"threat"*. --- ## Mistake 6 — Grammatical Errors That Repeat Across the Essay Grammatical Range & Accuracy penalises **frequent errors** more than occasional ones. One slip in a complex sentence is forgivable. The same subject-verb agreement mistake appearing six times signals a systematic gap — and that caps your grammar score. The most common recurring errors in Task 2: - **Subject-verb agreement with uncountable nouns** — *"The information are..."* should be *"The information is..."* - **Article misuse** — omitting *the* before a previously mentioned noun, or adding *a* before an uncountable noun - **Tense inconsistency** — switching between present and past when discussing a general truth - **Run-on sentences** — joining two independent clauses with only a comma The most efficient way to address this is to **proofread for one error type at a time** in the last two minutes. Scan only for article errors, then scan only for verb agreement. You will catch far more than a general re-read. --- ## Mistake 7 — Ignoring the Word Count (in Both Directions) The minimum for Task 2 is **250 words**. Writing below this is penalised explicitly under Task Response. But writing 450 words in 40 minutes almost always means less time for planning and proofreading — and a longer essay is not a better essay if the extra content is repetitive or irrelevant. A realistic, well-structured Task 2 essay sits between **270 and 320 words**. That is enough to develop two strong body paragraphs with an introduction and conclusion, without sacrificing quality for quantity. Time allocation matters here: spend **5 minutes planning**, **30 minutes writing**, and **5 minutes checking**. The planning step is not optional — it is what stops you from writing three sentences and realising you have argued yourself into a corner. --- ## Mistake 8 — A Conclusion That Just Repeats the Introduction A conclusion that paraphrases the introduction word-for-word adds nothing and signals to the examiner that you ran out of ideas. A strong conclusion does two things: **restates your position in fresh language** and **signals finality** without introducing a brand-new argument. > Weak conclusion: **"In conclusion, there are advantages and disadvantages to social media and governments should consider both sides."** > Strong conclusion: **"Ultimately, while the connective power of social media is undeniable, the evidence points clearly to a need for structured guidance — particularly for younger users — to ensure the technology serves wellbeing rather than undermining it."** The second version echoes the thesis, uses different vocabulary, and closes the argument decisively. --- ## Putting It All Together Every mistake above maps directly to one of the four marking criteria. That is not a coincidence — it is the design of the test. When you understand *why* each error costs marks, fixing it becomes a targeted decision rather than a guess. If I had to prioritise: get your **Task Response** right first. A clear, committed thesis and fully developed paragraphs that actually answer the question will do more for your band score than any vocabulary list. Everything else — cohesion, grammar, lexis — sits on top of a solid argumentative foundation. ## FAQ ### What is the minimum word count for IELTS Writing Task 2? The official minimum is 250 words. Writing below this is penalised under Task Response. Aim for 270–320 words for a well-developed essay without sacrificing quality for length. ### How is IELTS Writing Task 2 scored? Task 2 is marked on four criteria — Task Response, Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy — each worth 25% of your Writing band. Task 2 itself is double-weighted compared to Task 1. ### Why does misreading the question hurt my score so much? Misreading the question directly impacts Task Response, which is one of the four equally weighted criteria. An off-topic or partially answered essay can cap your Task Response at Band 5 regardless of how well-written the language is. ### Is using lots of transition words good for IELTS Writing? No — overusing connectors like 'Furthermore' and 'Moreover' is described as 'mechanical' in the IELTS marking descriptors and is penalised under Coherence & Cohesion. True cohesion comes from logical flow, pronoun reference, and varied sentence structure. ### How much time should I spend planning my Task 2 essay? Spend roughly 5 minutes planning, 30 minutes writing, and 5 minutes proofreading within your 40-minute Task 2 window. Planning prevents structural problems mid-essay and makes your argument more coherent from the start.
