Here's what catches most students off guard: you can write a grammatically perfect letter and still score a Band 6 instead of a Band 7. Why? Because your request isn't strong enough. The examiner reads awkward phrasing, weak modal verbs, and requests that sound confused. They know something's missing.
Most students focus on avoiding mistakes instead of building strength into their language. In IELTS Writing Task 1 letters—especially formal request letters—the gap between Band 6 and Band 7 comes down to one thing: how clearly and appropriately you ask for what you need.
Let me walk you through how to evaluate your own request strength, spot the weak patterns, and rewrite your way to Band 7 or higher.
A strong request is simultaneously direct and polite. It's specific. It doesn't apologize unnecessarily. It uses the right modal verbs and varies sentence structure. Most importantly, the examiner understands exactly what you want without having to guess.
Band 7 letters don't waffle. They don't use "I hope you could maybe possibly consider..." That's Band 5 language. Band 7 uses structured politeness with confidence.
Good: "I would appreciate it if you could provide a full refund within 14 days."
Weak: "I hope you could maybe give me back my money soon if that's okay."
See the difference? One is a request. The other is begging. Examiners mark Band 7 on Task Response, and that requires you to deliver what the prompt asks clearly.
Before you assess your own letter, know what you're looking for. Request strength breaks down into four measurable parts.
Score each element from 1-3. If you're averaging below 2.5, you're in Band 6 territory. Band 7 requires all four working together.
This is where examiners spot sophistication. Your modal verb choice tells them whether you understand register. In formal request letters, you're signaling confidence levels.
Band 7 strength: "I would be grateful if you would consider extending my deadline to June 15th."
Band 5-6: "Can you please give me more time? I really need it."
"Would" paired with "grateful" or "appreciate" creates formality without rudeness. "Can" is too casual and shifts the power dynamic awkwardly. In IELTS formal letters, knowing this difference is a Band 7 skill. That's what examiners are looking for.
The rule: use "could" and "would" for requests. Keep "can" and "will" for statements. Avoid "might"—it suggests lower probability and undermines your request.
Tip: Read your request aloud. If it sounds like you're asking a friend for a favor, change it. IELTS formal requests sound like you're acknowledging their authority while asserting your legitimate need.
Vague requests lose marks. Specific requests show you understand the communicative task. Let's use an actual IELTS scenario.
Prompt: "Write a letter to your employer requesting flexible working hours."
Weak: "I would like to ask if it's possible to work different hours sometime soon because I have some personal commitments."
Band 7: "I would like to request a flexible schedule, specifically working 8:00 AM to 3:30 PM Monday to Thursday and 9:00 AM to 5:00 PM on Fridays, effective from September 1st."
The second version shows you've thought through logistics. You're not dumping responsibility on your employer to figure out what you want. That's Band 7 Task Response.
Specificity also means adding numbers: refund amounts, dates, quantities, word counts. If your letter says "soon", replace it with a date. If it says "some time", give a number of hours or days. This isn't about being bossy. It's about being clear and professional.
This is the balancing act separating Band 6 from Band 7. You need to sound respectful without sounding desperate.
Weak politeness: "I'm really sorry to bother you, but would you mind possibly considering whether you might be able to help me if you have time?"
Strong politeness: "I understand that this request may require administrative effort. However, I would greatly appreciate your assistance in resolving this matter."
Band 7 politeness acknowledges the reader's position without self-deprecation. You're not over-apologizing. You're building a rational case. Compare the structures:
The strong version uses "I understand" instead of "I'm sorry". It uses "I would appreciate" instead of "would you mind if you could maybe". Totally different energy, same politeness level. That's what examiners score.
Band 5-6 writers bury requests inside conditional clauses. Band 7 writers put them in the main clause where they belong.
Weak structure: "If you might have the time and if it wouldn't be too much trouble, I was wondering whether you could possibly look into the possibility of providing a replacement."
Band 7 structure: "I would like to request a replacement product. Given that the current item is defective, I believe this is a reasonable request."
In the good version, the request is the main clause. Everything else supports it. In the weak version, the request hides inside layers of conditional language. Your examiner shouldn't have to dig to find what you want.
Tip: Write your request first, then add supporting sentences. If you find yourself writing more than 15 words before stating what you want, rewrite it. Band 7 uses clarity over complexity.
You don't need a tool to evaluate your request strength. Do this yourself using a simple framework. Read your letter and answer these questions for each request you make.
Score yourself: 5/5 = Band 7 request strength. 4/5 = Band 6-7 borderline. 3/5 or below = Band 5-6.
If you scored below 4, revise that request before submitting. Most Band 6 essays have one weak request that pulls the whole Task Response score down. Our IELTS writing checker evaluates request strength alongside other criteria, giving you detailed feedback on each element.
Let's take an actual type of IELTS Task 1 prompt: a complaint letter where you request compensation.
The scenario: You bought a laptop online. It arrived damaged. Write to the company requesting a replacement or refund.
Band 5: "I am writing to say that my laptop is broken. It came like this and I want a new one. Can you send me another laptop please? I need it for work. Please let me know what you can do."
Band 7: "I am writing to lodge a formal complaint regarding order number 45892, purchased on August 15th. The laptop arrived with a cracked screen and non-functional keyboard, rendering it unusable. I would like to request either a full replacement or a refund of £1,299.99 within 14 days. Given that I require this device for work, I would appreciate your urgent attention to this matter."
Compare them on four dimensions:
That difference is worth roughly 1 full band. For a deeper look at how tone affects complaint letters specifically, check out our guide on IELTS writing correction for complaint letters.
Watch for these patterns in your own writing. They're Band 5-6 habits that are easy to fix once you see them.
Mistake 1: Hedging everything. "I was wondering if you might possibly consider..." This isn't politeness. It's uncertainty. Band 7 is polite and sure. "I would appreciate your assistance with..." is polite and direct.
Mistake 2: Over-apologizing. "I'm so sorry to bother you, I'm really sorry, I apologize in advance..." One apology is enough. Zero is fine if your request is reasonable. More than one signals weakness.
Mistake 3: Using the wrong prepositions. "Unfortunately, I need this resolved quickly" sounds like you're blaming yourself. "However, given the urgency, I request..." sounds professional. Word choice matters more than you think.
Mistake 4: Making requests sound optional. "If you could, would you mind possibly sending me...?" Band 7 rephrases this: "I request that you send me..." or "I would like you to send me..." The reader knows it's a request because your grammar matches the context. If your letter uses too much indirect phrasing, an essay checker can flag it immediately.
Tip: Read your letter aloud once. If you sound like you're begging, rewrite. If you sound like you're ordering someone around, rewrite. Band 7 sounds like a professional having a conversation with someone in a position to help.
Examiners don't just check if your letter has a request. They evaluate how well you communicate that request. A weak request suggests you don't understand how to influence or persuade in English. A strong request proves you can think strategically about language.
This is the difference between students who plateau at Band 6 and those who break into Band 7. It's not bigger vocabulary. It's not longer sentences. It's choosing the right words in the right positions, and backing them up with specifics.
