IELTS Writing: The 20 Most Common Mistakes and How to Fix Them

## What are the most common IELTS Writing mistakes? The 20 most common IELTS Writing mistakes cluster in four areas: **Task Response** (not answering the prompt fully), **Coherence and Cohesion** (weak paragraph structure), **Lexical Resource** (repetitive or imprecise vocabulary), and **Grammatical Range and Accuracy** (limited sentence variety, recurring grammar errors). These four are also the four scoring criteria for Writing — each worth 25% of the band score ([IELTS Writing Band Descriptors, 2024][1]). Around 60% of IELTS Writing candidates score Band 6.0 or below, mostly because of recurring versions of these mistakes ([IELTS Test Taker Report, 2024][2]). ### Key statistics - **2024 IELTS Academic Writing mean band:** 5.9 ([IELTS, 2024][2]) - **% of test-takers scoring Band 6.0 or lower in Writing:** ~60% ([IELTS, 2024][2]) - **Each criterion = 25% of Writing score** ([IELTS, 2024][1]) - **Average lift from systematic error correction over 4 weeks:** 0.5 band ([Cambridge English IELTS Research, 2024][3]) ## What are the 5 most common Task Response mistakes? 1. **Not answering all parts of the question.** Task 2 prompts often have 2-3 parts (discuss both views, give your opinion, give an example). Missing one part caps your Task Response at Band 6.0. 2. **Going off-topic.** Stay strictly on the prompt. Even one paragraph of unrelated content lowers your score. 3. **Writing under the word limit.** Task 1 minimum is 150 words; Task 2 minimum is 250. Under-length essays are penalized. 4. **Not stating a clear position in Task 2.** Your introduction must include a thesis sentence that takes a position. 5. **Generic examples.** "Many studies show..." without specifics weakens Task Response. Use named examples or specific contexts. ## What are the 5 most common Coherence and Cohesion mistakes? 6. **Overusing "Firstly, Secondly, Thirdly".** Examiners flag mechanical linking. Use a mix: *To begin with*, *In addition*, *On the other hand*, *As a result*. 7. **One-sentence paragraphs.** Each body paragraph should be 4-6 sentences with a clear topic sentence. 8. **No topic sentence.** Every paragraph must open with a sentence stating the paragraph's main idea. 9. **Pronoun reference unclear.** "It" or "this" without a clear referent confuses the examiner. Repeat the noun if needed. 10. **Conclusion that introduces a new idea.** The conclusion should restate your position and summarize the main points only. ## What are the 5 most common Lexical Resource mistakes? 11. **Repeating the same word 3+ times.** Use synonyms or rephrase. *Children → kids → young people*. 12. **Misused "thesaurus words".** Replacing "important" with "quintessential" if you don't know the precise meaning lowers your score. Examiners spot misused vocabulary. 13. **Wrong collocations.** *Make a research* (wrong) → *do/conduct research* (right). Memorize collocations as units. 14. **Informal vocabulary in formal Task 2.** Avoid contractions, slang, and phrasal verbs that have a formal alternative (*find out → discover*). 15. **Spelling errors.** Repeated spelling errors of common words lower Lexical Resource. Proofread carefully. ## What are the 5 most common Grammar mistakes? 16. **Subject-verb agreement.** *The number of students are increasing* (wrong) → *is increasing* (right). "Number of" takes singular. 17. **Article errors.** Missing or wrong *a*, *an*, *the*. *Government should support education* → *The government should support education*. 18. **Run-on sentences.** Joining two independent clauses with a comma. Use a period, semicolon, or coordinating conjunction. 19. **Limited sentence variety.** Band 7+ requires a mix of simple, compound, and complex sentences. Aim for at least 3 complex sentences per essay. 20. **Verb tense inconsistency.** Switching between past and present without reason. Stay in the same tense unless time-shifting is meaningful. ## How do I self-edit my IELTS essay? Use this 5-step self-edit checklist after writing: 1. **Word count check** — Task 1 ≥ 150 words; Task 2 ≥ 250 words 2. **Question check** — every part of the prompt is addressed 3. **Paragraph check** — each paragraph has a topic sentence and 4-6 sentences 4. **Vocabulary check** — no word repeated 3+ times; collocations checked 5. **Grammar check** — subject-verb agreement, articles, and tenses > "Most candidates can lift their Writing band by 0.5 in 4 weeks just by systematically correcting the same 5-7 errors that appear in every essay." — Pauline Cullen, *Writing for IELTS Advanced* ([Cullen, Cambridge University Press, 2024][4]) ## How should I structure 4 weeks of practice? | Week | Focus | Daily target | |------|-------|--------------| | 1 | Diagnostic essay + error log setup | 1 essay | | 2 | Task 1 chart description language + 2 essays | 2 essays + drills | | 3 | Task 2 framework + 3 essays | 3 essays + drills | | 4 | Timed full Writing tests (60 min) + final review | 2 timed tests | ## Common questions about IELTS Writing mistakes **How many essays should I write before my test?** Aim for 15-20 timed essays over 4-8 weeks, with detailed feedback on at least 6 of them. **Should I memorize Task 2 templates?** Memorize structures (introduction, body, conclusion) but not full sentences. Memorized phrases are detected and lower Coherence and Lexical Resource scores. **Can I use "I" in Task 2?** Yes — IELTS Task 2 explicitly invites your opinion. *In my view*, *I believe*, *I would argue* are all acceptable. **Is American or British spelling preferred?** Both are accepted. Be consistent within a single essay (don't mix *colour* and *color*). **How important is handwriting on paper-based IELTS?** Examiners must be able to read your essay. Illegible handwriting is marked down on Task Achievement and Coherence, even if the content is good. **How is the General Training Writing different from Academic?** Task 1 is a letter (formal, semi-formal, or informal) instead of a chart description. Task 2 is identical in format. The same 20 mistakes apply to both. ## Sources 1.
