Why you're stuck at Band 6.5 in IELTS Writing — and the exact fixes
If you keep landing on 6.5, the problem is almost never "you need fancier words." It's usually three or four small, repeated habits that quietly cap each criterion at 6. Find them, fix them, and 6.5 becomes 7.
1. Grammar accuracy — the most common 6.5 trap
Band 7 for Grammatical Range & Accuracy needs a variety of complex sentences and frequent error-free sentences. Across 250+ words, that's hard — a handful of small slips is enough to hold you at 6. The usual culprits are tiny and repeated:
The fix: stop hunting for "advanced" structures and start eliminating repeat errors. Most candidates make the same 3–4 mistakes (articles, prepositions, subject–verb agreement, word form) over and over. Fix those and your accuracy jumps a whole band.
2. Task Response — you answered around the question, not all of it
The single most common reason a strong-sounding essay scores 6 is Task Response: the candidate read the prompt too fast and missed a part of it. If the question asks for causes and solutions and you mostly wrote causes, you're capped — no matter how good the English is.
The fix: before writing, underline every task in the prompt ("discuss both views", "and give your opinion", "what problems", "to what extent"). Make sure your essay has a clear, consistent position and a paragraph for each part. A fully-answered 6-vocabulary essay beats a half-answered 7-vocabulary one.
3. Coherence & Cohesion — linking words bolted on, not flow
Many 6.5 essays sprinkle "Moreover, Furthermore, In addition" at the start of every paragraph. Examiners notice mechanical linking and it doesn't lift you. Band 7 is about ideas that genuinely connect and paragraphs with one clear central point each.
The fix: one clear idea per paragraph, stated in the first sentence, then explained and supported. Use linking words only where they reflect a real relationship (contrast, cause, result) — not as decoration.
4. Vocabulary — accuracy beats "impressive"
Reaching for big words you don't fully control usually lowers your score, because misused collocations are errors. Band 7 Lexical Resource wants some less-common vocabulary used naturally and correctly — not a thesaurus dump.
The fix: use precise, topic-specific words you're sure of. Correct and clear outscores fancy and wrong, every time.
So how do you find your 3–4 habits?
You can't fix what you can't see — and you won't spot your own repeated errors by re-reading your essay, because they look normal to you. That's the whole point of a strict, honest examiner: it names your true band, quotes the exact sentences holding you back, and shows the smallest edits that lift you.
Then do the loop that actually works: get your honest band → apply the suggested edits → re-mark → watch it climb. Practising blind keeps you at 6.5; practising with honest, specific feedback is how 6.5 becomes 7.
