You've drilled grammar for weeks. Your sentence structures are solid. But then you write a request letter and the examiner marks you down for "inappropriate register" or "overly direct tone." You read the feedback confused. Your English felt polite to you.
Here's what actually happened: you confused grammatical correctness with tone. A sentence can be perfectly grammatical and still sound rude, demanding, or too casual for a formal request letter.
The gap between Band 6 and Band 7 in IELTS Task 1 isn't grammar. It's tone.
The IELTS band descriptors measure something called Task Response. Band 7 requires "appropriate register and tone." Band 6 allows "mostly appropriate register"—which means examiners catch inconsistency.
Here's the brutal truth: you could write zero grammar errors and still score Band 6 if your letter sounds demanding, angry, or inappropriately casual. The reverse isn't true. You can't score Band 7 without nailing tone.
Most IELTS Task 1 letters fall into one of three categories: requests, complaints, or information inquiries. Each has its own tone rules. When you confuse them, examiners notice.
Real talk: Tone isn't built by adding "please" to a sentence. It comes from word choice, sentence structure, and how you frame requests. You need all three working together.
Band 5 and 6 writers make the same three errors repeatedly. Once you know them, fixing your letters becomes automatic.
This is the biggest tone killer.
Band 5: "Send me information about your courses immediately. I need to know the fees and start dates."
Why fails? The imperatives (Send, I need) sound like commands, not requests. They subordinate the reader. There's zero indirectness.
Band 7: "I would appreciate it if you could provide information about your courses. Could you also include details about fees and start dates?"
See what changed? Conditionals (would, could) and question forms replace commands. You're asking, not demanding. That's Band 7 letter tone.
Register confusion tanks scores fast.
Band 5: "I am writing to inform you that the hotel room was totally disgusting. The bathroom was gross and the staff weren't helpful at all."
Your opening is formal. Then it collapses into casual language (gross, totally). Examiners mark this down instantly for inconsistent register.
Band 7: "I am writing to lodge a complaint about my recent stay. The room conditions fell below acceptable standards, particularly the bathroom facilities, and the staff did not provide adequate assistance."
Consistent formality throughout. No slang. No contractions. No conversational phrases creeping in.
Even when complaining, you can't sound angry.
Band 5: "Your company clearly doesn't care about customers. You messed up my booking and ruined my holiday."
Too accusatory. Reads like you're texting a friend, not writing a formal letter.
Band 7: "Unfortunately, there appears to have been an error with my booking, which has caused significant inconvenience. I would be grateful if you could investigate this matter and advise on how we might resolve it."
Same complaint, different approach. You're calm. You're professional. You're solution-focused. That's Band 7 tone.
English formality isn't on/off. It's a spectrum. Band 7 letters sit in the "politely indirect" zone.
Most students under-correct. They stay too direct. Band 7 requires you to soften your language without sounding like you're from the 1800s.
The fix: Use conditionals (would, could, might) and question forms instead of imperatives. These automatically adjust your tone without extra work.
Examiners see these patterns in Band 7 letters. You don't need all nine, but using 4-6 consistently is the target.
Would, could, might instead of will, can, must.
Weak: "I will need this urgently."
Strong: "I would appreciate this at your earliest convenience."
Turn demands into questions.
Weak: "Give me the refund within 14 days."
Strong: "Could you process the refund within 14 days?"
Removes blame. Sounds more objective.
Weak: "You didn't send the invoice on time."
Strong: "The invoice was not received by the agreed date."
I would appreciate, I would be grateful, I wonder if, it would be most helpful.
Weak: "Tell me when the course starts."
Strong: "I wonder if you could inform me when the course begins."
Unfortunately, regrettably, apparently, seemingly.
Weak: "The room was broken."
Strong: "The room appears to have been damaged."
Creates conditionality and softens requests.
Weak: "I need the information now."
Strong: "If it is not too much trouble, I would need this information by Friday."
Lodge a complaint (not complain), advise (not tell), considerable (not big), enquire (not ask).
However, nevertheless, in addition, as a result. Avoid informal connectors like but, and, so in formal letters.
Yours faithfully (unknown recipient) or Yours sincerely (known recipient).
Let's see this in action. The prompt: "You want to take a course at a local college. Write a letter requesting information about course details and fees."
Dear Sir or Madam,
I am writing to ask about the courses at your college. I want to know about the course details and the fees. Please tell me when the courses start and how long they take. Also, I need to know the cost of the course.
I will be grateful if you send this information to me quickly because I need to decide soon.
Thank you,
Yours sincerely
Problems: Too many direct requests (I want, I need, Please tell). No indirectness. Repetitive (fees mentioned twice). Sounds demanding, not polite.
Dear Sir or Madam,
I am writing to inquire about the courses currently available at your institution. I would be grateful if you could provide me with information regarding course content, duration, and fees.
Additionally, it would be most helpful if you could advise me on the course start dates and whether flexible payment options are available. If possible, I would also appreciate details about any entry requirements.
I would be most grateful for your prompt response, as I am keen to commence my studies in the coming months.
Yours faithfully
What changed: Conditionals (would be grateful, could provide). Question forms (could advise). Softening adverbs (most helpful). Formal vocabulary (inquire instead of ask, institution instead of college). Consistent structure. Same content. Completely different tone.
You don't need external tools. This three-step tone audit takes three minutes and catches the mistakes that drop you from Band 7 to Band 6.
Highlight every sentence starting with a verb: Send, Tell, Give, Show, Provide. Count them. More than three in a full letter? Your tone is too direct. Rewrite at least half as questions or conditional statements.
Look for conversational words: really, very, nice, bad, good, okay, stuff. Replace each. Really = considerably. Nice = pleasant. Bad = unsatisfactory. Good = appropriate. Stuff = items.
Read paragraph by paragraph. Does your tone stay the same? Or do you shift from formal to casual? One casual sentence can drop you from Band 7 to Band 6. Examiners catch it instantly.
Common mistake: Sounding entitled or demanding.
The fix: Use "would appreciate," "could you," and "if possible." These soften requests automatically.
Common mistake: Sounding angry or accusatory.
The fix: Use passive constructions. Say "there appears to have been an issue" instead of "you made a mistake." Use "I would be grateful if you could investigate" instead of "fix this now."
Common mistake: Sounding insincere or over-the-top.
The fix: Use measured language. "Thank you for your assistance" works. "You have literally changed my life" doesn't (unless you're genuinely applying to university).
You have 20 minutes for Task 1. Allocate them like this: 3 minutes planning, 13 minutes writing, 4 minutes checking. In those final 4 minutes, use the tone audit above. Focus on the three mistakes: imperatives, vocabulary consistency, and register shifts. Fix what you can.
Start with your next practice letter. Write it normally. Then spend 3 minutes on the tone audit: highlight imperatives, check vocabulary, verify register consistency. Rewrite the problem sentences using conditionals and questions.
Do this for 5 letters. The patterns become automatic. After that, you'll catch tone errors while writing, not after.
