03 · IELTS Band 7+ Writing Strategies¶
Level 2 covered the basic structure for Task 1 and Task 2. This module covers what specifically pushes a competent, correct essay from Band 6 into Band 7+ territory — mainly cohesion quality, sentence variety, and precision of vocabulary rather than simply "more advanced words."
1. What separates Band 6 from Band 7+ in Writing¶
| Criterion | Band 6 | Band 7+ |
|---|---|---|
| Task Achievement/Response | Addresses the task, some parts underdeveloped | Covers all parts fully, clear position, well-supported |
| Coherence and Cohesion | Uses linking words, sometimes mechanically or overused | Uses cohesion flexibly; paragraphing is logical and clear |
| Lexical Resource | Adequate range, some errors with less common words | Flexible use of less common vocabulary, occasional errors don't impede meaning |
| Grammatical Range and Accuracy | Mix of simple/complex sentences, frequent errors | Wide range of structures, majority error-free |
2. Cohesion without over-using linking words¶
A common Band 6 pattern is starting every sentence with "Firstly," "Moreover," "In addition" — mechanically correct but repetitive. Band 7+ writing achieves cohesion through varied connection methods.
| Band 6 (repetitive) | Band 7+ (varied cohesion) |
|---|---|
| "Firstly, pollution increases. Secondly, health problems increase." | "Pollution increases sharply, which in turn drives up rates of respiratory illness." |
| "Moreover, costs rise. In addition, quality falls." | "Costs rise, often at the expense of quality." |
| Referring back with "This is..." repeated every paragraph | Varying reference: "This trend," "Such a shift," "The result of this..." |
3. Precision over "impressive" vocabulary¶
Band 7+ raters specifically reward precise word choice, not necessarily rare words. A precise, correctly-used common word beats an impressive but slightly-wrong sophisticated one.
| Imprecise | Precise |
|---|---|
| "This is a big problem for society." | "This poses a significant challenge for policymakers." |
| "The government should do something about it." | "The government should intervene through targeted regulation." |
| "It has a good effect on the economy." | "It has a measurable, positive impact on economic growth." |
4. Sentence variety, deliberately¶
| Type | Example |
|---|---|
| Simple | "Remote work has become common." |
| Compound | "Remote work has become common, and many companies now offer it permanently." |
| Complex (subordinate clause) | "Although remote work has become common, some companies still resist it." |
| Complex (relative clause) | "Remote work, which was once considered a temporary measure, has become permanent for many companies." |
Aim to include at least one of each sentence type per body paragraph — this variety is exactly what Grammatical Range descriptors reward.
5. Worked example — upgrading a Band 6 paragraph to Band 7+¶
Band 6 version: "Firstly, technology has changed education. This is because students can learn online now. Secondly, this is good because it saves time. Moreover, it is cheaper than traditional classes."
Band 7+ version: "Technology has fundamentally reshaped education, largely because students can now access high-quality instruction online rather than being tied to a physical classroom. This shift offers two clear advantages: it saves considerable time, since learners no longer need to commute, and it is typically far cheaper than traditional in-person courses."
The upgraded version removes mechanical "firstly/secondly," combines ideas into varied sentence structures, and uses precise vocabulary ("fundamentally reshaped," "tied to," "considerable") instead of vague ones ("big," "good," "change").
6. Cheat sheet — Band 7+ writing checklist¶
| Check | Why it matters |
|---|---|
| Did I vary my cohesive devices instead of repeating "firstly/moreover"? | Rewarded specifically under Coherence and Cohesion |
| Did I choose precise words over merely "impressive" ones? | Precision with control outscores sophistication with errors |
| Does each paragraph include at least two different sentence types? | Demonstrates Grammatical Range directly |
| Did I fully address every part of the task, not just the easiest part? | Task Achievement/Response caps the score if any part is skipped |
How It Actually Works¶
Mechanical connectives like "Firstly... Secondly... Moreover..." mark additive cohesion — they signal only that another item is being added to a list, without specifying how the items actually relate. The Band 7+ rewrite ("Pollution increases sharply, which in turn drives up rates of respiratory illness") instead uses causal cohesion — "in turn" encodes an actual causal chain between the two clauses. This is not merely stylistic variety: it demonstrates that you can express logical relationships (cause, contrast, consequence) as an integrated part of sentence grammar rather than bolting a generic list-marker onto otherwise unconnected sentences, which is exactly the distinction the rubric's phrase "cohesion used flexibly" is pointing at — flexible means matching the cohesive device to the actual logical relationship, not having a bigger stock of transition words.
The precision-over-impressiveness principle reflects how raters assess lexical control, not lexical rarity. A word carries a very specific package of meaning, connotation, and typical collocates; "pose a challenge" and "is a problem" differ not in formality alone but in precise scope — "challenge" implies something surmountable and often implies agency (who must address it), while "problem" is neutral and open-ended. Choosing the word whose exact meaning matches your intended claim signals that your internal representation of the word's meaning is accurate and complete, whereas reaching for an impressive synonym without matching its precise sense reveals you're pattern-matching "sounds sophisticated" rather than genuinely knowing the word — and raters are specifically trained to catch that gap.
Sentence-type variety is scored because different syntactic structures encode different logical relationships as grammar rather than as separate sentences: a subordinate clause ("Although X, Y") builds concession directly into a single sentence's structure, while two simple sentences describing the same content force the reader to infer that relationship themselves. Producing this range demonstrates you can choose the grammatical structure that matches your intended logical relationship on demand, rather than defaulting to the one structure (usually simple, coordinate sentences) that's easiest to retrieve — which is the concrete, testable meaning behind "grammatical range."
Exercise¶
Take an essay paragraph you've written before (from Level 2's Task 2 module) and rewrite it applying sections 2-4: replace at least two mechanical linking words with varied cohesion, replace two vague words with precise alternatives, and ensure the paragraph contains at least three different sentence types.
