You're stuck at Band 5. You keep getting 5.5, maybe 6.0 on a good day. You write the letter. It reads okay. The grammar's decent. So why isn't the examiner pushing you to Band 6?
Here's what most people miss: Band 5 to Band 6 isn't about becoming a better writer. It's about being more precise. Most Band 5 letters have loose task response, fuzzy tone, or weak organisation that examiners spot in seconds. The gap between "okay" and "good" is smaller than you think, but you need to know exactly what to tighten.
This post shows you what that gap looks like in real writing. You'll see actual Band 5 weaknesses, how to catch them in your own letters, and the specific moves that push you into Band 6. If you want instant feedback on your letter, our free IELTS writing checker identifies these exact weaknesses in seconds.
Let's be straight about this: Band 5 (5.0 to 5.5) means you've done the task, but not well enough. Band 6 means you've done it well. Here's what the IELTS examiners actually assess:
Band 5 writers usually stumble hardest on Task Response and Coherence. They do address the prompt, but loosely. They use connectors, but clumsily. Band 6 writers tighten both down completely.
You write something, read it back, and it feels fine. That's Band 5 thinking. Band 5 writers address the prompt. They just don't go deep enough.
Here's an actual IELTS General Training prompt:
Situation: You have recently moved to a new town. Write a letter to a friend describing your new accommodation and asking about their recent job interview.
Bullet points:
- Describe where you live now
- Describe what you like about your accommodation
- Ask about their job interview
Here's a Band 5 response:
Weak: I live in a nice flat near the city centre. I like my accommodation because it is comfortable and the rent is good. How did your interview go? I hope you got the job.
Each bullet point gets one sentence. No specifics. No real information. An examiner reads this and immediately thinks: "That's it? I learned almost nothing."
Now look at Band 6:
Good: I've just moved into a two-bedroom flat in the Riverside area, about 15 minutes from the city centre by bus. What I love most is the large kitchen and the private balcony overlooking the park. The neighbourhood is quiet, and there are several cafes and shops within walking distance, which makes daily life quite convenient. By the way, how did your interview at the marketing firm go last month? I've been eager to hear whether you impressed them with your portfolio.
Notice: specific locations, concrete details (two-bedroom, balcony, 15 minutes by bus), reasons why things matter (quiet neighbourhood, shops nearby). The follow-up question asks for specifics too (mentions the company, the portfolio). This is what Band 6 task response looks like.
Tip: For each bullet point in the prompt, write at least 2-3 sentences. One sentence per point screams Band 5. If you catch yourself writing one sentence per bullet, stop and add detail: specific facts, reasons, examples that actually matter.
Band 5 writers know paragraphs exist. They just don't know how to use them strategically. Ideas jump around. Paragraphs are either too crammed or too thin. Nothing connects properly.
Here's Band 5 in action:
Weak: I moved to London last month. My flat is near the station. I have a bedroom and a living room. The kitchen is small but clean. I like the neighbourhood. There are restaurants near my flat. I go to the park on weekends. My job is good. I work in marketing. What about your job? Did you find a new company?
This reads like a shopping list. No paragraphing. Ideas scatter everywhere (flat, neighbourhood, job, then suddenly their job). Sentences don't link. You can understand each one, but the letter has no flow.
Band 6 organises it like this:
Paragraph 1 (Opening): Opening line + reason for writing
Paragraph 2: Accommodation details (what it's like, why you like it)
Paragraph 3: Follow-up question about their situation
Paragraph 4 (Closing): Hope to hear from you soon + sign-off
Band 6 writers link ideas with connectors: "In addition to," "As a result," "However," "For this reason." These words guide the reader. The letter flows instead of jumping around.
Tip: Plan your letter before you start. Each bullet point in the prompt becomes its own paragraph. Link paragraphs with sentence starters: "As I mentioned," "In addition," "Speaking of." This single move bumps you into Band 6 on Coherence & Cohesion.
Band 5 vocabulary isn't wrong. It's just flat. You use "nice" four times. Every paragraph starts with "I think." You repeat "very good."
Compare these two descriptions of an apartment:
Weak: My flat is nice. The location is nice. The room is nice. The neighbours are nice. It is a nice place to live.
"Nice" tells the examiner nothing. Is it peaceful? Beautiful? Convenient? Affordable? Band 5 writers pay a penalty for this on Lexical Resource because you're not showing word choice ability.
Good: My flat is spacious and well-lit, overlooking the main square. The location is highly convenient, with shops and restaurants within walking distance. The bedroom is tranquil, away from street noise. The neighbours are friendly and considerate. Overall, it's an ideal neighbourhood for someone wanting urban access without the constant hustle.
Same idea, different words: spacious, well-lit, convenient, tranquil, friendly, ideal. Each word carries specific meaning. The examiner reads this and thinks: "This person knows how to choose words precisely."
Here's the fix: when you finish writing, search for words you've used three or more times. Find replacements. "Nice" becomes "pleasant," "agreeable," "comfortable," "charming," or "delightful." "Very good" becomes "excellent," "outstanding," or "impressive."
Tip: Keep a quick list while you write. Every time you use a basic word (nice, good, bad, very, thing, place), jot it down. When you finish, replace repeats with a thesaurus. This one habit moves most Band 5 writers straight into Band 6 on Lexical Resource, and the same principle applies whether you're checking a letter, essay, or any IELTS writing correction task.
Band 5 grammar isn't broken. It's sloppy. Most words are spelled right. Most sentences make sense. But the same errors show up again and again, and examiners notice on the second read.
The most common Band 5 grammar traps:
Band 6 writers rarely make these mistakes. More importantly, they use more complex sentence structures: conditionals, passive voice, relative clauses strung together.
Example:
Weak: I like my flat because it is near shops. The shops have everything I need. I go there often.
Good: What appeals to me most is the proximity to local shops, where I can find virtually everything I need without travelling far.
The Band 6 version combines three Band 5 sentences into one sophisticated structure using a relative clause ("where I can find..."). That's Grammatical Range.
Tip: Read your letter out loud when you finish. If you stumble on a sentence, it probably has a grammar issue. Fix it. Then check: Does every paragraph have at least one sentence that's more complex than "Subject + verb + object"? If not, add a relative clause or condition to one sentence per paragraph.
IELTS Task 1 tone depends entirely on your audience. Writing to a friend? Casual is fine. Writing to a company or government office? Formal register. Band 5 writers often get this wrong or hover awkwardly between casual and formal.
Example: You're writing to a landlord about a broken tap.
Weak (tone mismatch): Hey there, so like, the bathroom tap is kinda broken and it's super annoying. Can you fix it soon? Thanks loads!
Too casual for a landlord. "Hey there," "kinda," and "super annoying" would never work with someone in a formal position over you.
Good: I'm writing to inform you of a maintenance issue in the bathroom. The tap has developed a fault and requires repair. I would appreciate it if you could address this at your earliest convenience. Thank you for your attention to this matter.
Formal, clear, respectful. That's Band 6 register control. When writing to friends, Band 5 writers sometimes go too formal, which sounds robotic and stiff. Band 6 writers match the relationship: warmer, more conversational, but still grammatically solid and coherent.
This isn't a writing weakness. It's a test strategy problem. Many Band 5 writers spend 25 minutes writing and 5 minutes proofreading (or zero). Band 6 writers flip this: they write efficiently and spend 8-10 minutes reading through carefully for errors.
What should you look for in a 10-minute proofread?
You're not rewriting whole paragraphs. You're catching the repeatable mistakes that cost you points on Grammatical Range & Accuracy.
Tip: In your actual IELTS test, you have 20 minutes for Task 1. Spend 12 minutes writing and 8 minutes proofreading. Read your letter backward, sentence by sentence, to catch errors your brain would otherwise skip over.
You don't need a fancy tool to catch Band 5 patterns. Use this simple checklist after you finish each letter:
Run through this checklist on every practice letter. After three or four weeks, these habits become automatic, and your band jumps.
Band 5 to Band 6 isn't about talent. It's about repetition. You're training yourself to automatically spot vague answers, weak coherence, and repetitive words. After you've done this 10 times, it becomes automatic.
Here's a realistic practice schedule:
By week six, your writing should tighten up noticeably. Examiners spot tightness. Tightness is Band 6.
Stop adding more complexity. Instead, tighten what you have. Here's what moves the needle:
1. Replace vague words with specific ones. "Nice" becomes "spacious." "Good" becomes "reliable." This takes five minutes per letter and bumps Lexical Resource immediately.
2. Add one sentence of extra detail per bullet point. Don't write longer. Write more specific. "The flat is in a quiet area" becomes "The flat is in a quiet residential area near Richmond Park, which I walk through most mornings."
3. Link paragraphs with actual connectors. Not "Furthermore." Something that sounds like a real person: "As I mentioned," "Speaking of," "On another note." This kills coherence weaknesses instantly.
4. Combine short sentences into one complex sentence. "I live near shops. The shops have everything. I don't need to travel far" becomes "Because I live near shops that stock virtually everything, I rarely need to travel far." This adds Grammatical Range.
5. Use your 10-minute proofread to catch subject-verb agreement and tense consistency. These are the errors examiners count. Fix them and you're solid on accuracy.
