What Grammar Gets You Each Band

Band 5

Mostly simple sentences. Errors in complex structures. Limited range. Frequent errors in verb tense and agreement.

Band 6

Mix of simple and complex sentences. Some errors in complex structures. Attempts at linking devices β€” sometimes incorrect.

Band 7

Good range of complex structures. Most sentences are error-free. Occasional errors in complex grammar. Uses cohesive devices accurately.

Band 8

Wide range of structures. Most sentences are error-free. Inversions, participle clauses, non-defining relative clauses used correctly.

8 Grammar Rules β€” Ranked by Band Impact

Each rule shows the band it unlocks and the exact transformation needed.

1Formal Register β€” Eliminate Informal LanguageBand 5β†’6

IELTS Task 2 requires academic/formal register. Contractions, colloquialisms, and first-person opinions must be replaced with formal alternatives.

Avoid

I think this is a big problem. / It's really bad. / Lots of people...

Use Instead

This issue poses a significant challenge. / A large proportion of the population...

2Hedging Language β€” Avoid Absolute ClaimsBand 6β†’7

Never state an unsupported claim as absolute fact. Use hedging to signal your claim is an argument, not a law of nature. This shows sophistication.

Avoid

Technology always helps education. / Crime definitely increases with poverty.

Use Instead

Technology tends to enhance learning outcomes. / Poverty may be associated with higher crime rates.

3Complex Sentences with Subordinate ClausesBand 6β†’7

Band 7 requires a mix of simple, compound, and complex sentences. Subordinate clauses (although, while, because, if, since, unless) add grammatical range.

Avoid

Urbanisation causes pollution. It also causes traffic congestion. Both are problems.

Use Instead

Although urbanisation drives economic growth, it simultaneously exacerbates pollution and strains urban infrastructure.

4Passive Voice for Task 1 & Impersonal Task 2Band 6β†’7

Passive voice is used in Task 1 to describe data without a subject, and in Task 2 to achieve impersonal register when 'it is' constructions fit.

Avoid

We can see from the graph that sales rose. / People should address this issue.

Use Instead

The data reveals a steady rise in sales. / It is widely acknowledged that this issue must be addressed.

5Inversion for Emphasis (Not Only… But Also)Band 7β†’8

'Not only' triggers subject-auxiliary inversion in the first clause. This is a Band 7+ structure that demonstrates grammatical range.

Avoid

Not only urbanisation causes pollution, but it also strains infrastructure.

Use Instead

Not only does urbanisation cause pollution, but it also strains urban infrastructure.

6Non-defining Relative ClausesBand 7β†’8

Non-defining relative clauses (set off with commas) add information about a noun without restricting it. They use 'which' for things, 'who' for people β€” never 'that'.

Avoid

The policy which the government introduced is controversial. (defining β€” no commas, 'that' possible)

Use Instead

The new policy, which was introduced in 2024, has generated significant debate.

7Participle Clauses β€” Avoiding Dangling ModifiersBand 7β†’8

Participial phrases must share their implied subject with the main clause. If they don't, they 'dangle'. This is a key Band 7+ error to eliminate.

Avoid

Having analysed the data, the trend is clear. (who analysed? β€” the trend?)

Use Instead

Having analysed the data, researchers identified a clear upward trend.

8Cohesive Devices β€” Use PreciselyBand 6β†’7

Wrong cohesive device is worse than none. Match the device to its logical function: addition, contrast, result, example, or concession.

Avoid

Furthermore, this has drawbacks. (furthermore = addition, not contrast)

Use Instead

Nevertheless, this approach has significant drawbacks. (nevertheless = contrast/concession)

Cohesive Devices β€” By Function

The examiner checks that you use the right device for the right logical relationship β€” not just that you used any device.

FunctionDevices to use
AdditionFurthermore, Moreover, In addition, Additionally, Also
ContrastHowever, Nevertheless, Nonetheless, On the other hand, In contrast, Yet
ConcessionAlthough, While, Even though, Despite the fact that, Admittedly
Result/ConclusionTherefore, Consequently, As a result, Hence, Thus
ExampleFor instance, For example, Such as, To illustrate
EmphasisIndeed, In particular, Notably, Significantly
Summary/ConclusionIn conclusion, To summarise, Overall, In brief

5 Most Common Task 2 Grammar Errors

Error 1: Starting sentences with 'I think' or 'I believe'

Use 'It is argued that...', 'It is widely believed that...', or state it as a claim without 'I think'.

Error 2: Using 'furthermore' for contrast

'Furthermore' adds a similar point. For contrast, use 'However', 'Nevertheless', 'On the other hand'.

Error 3: 'Not only' without inversion

After 'Not only', always invert: 'Not only does [subject] [verb]...', not 'Not only [subject] [verb]...'.

Error 4: Dangling participle clauses

The subject of the participle phrase must match the main clause subject. 'Having analysed the data, I found...' β€” not '...the trend is clear.'

Error 5: Concluding with 'In conclusion, this essay has discussed...'

Don't describe your essay in the conclusion β€” state your final position. 'In conclusion, [your stance] because [reason].'
