Grammatical range and accuracy is measured on two different dimensions at once: the range of structures used (how much variety?) i.e., and the accuracy of which they are executed (which correct? ). Examiners award Band 6 for accurate simple sentences with some errors in attempts at band 6 complex structures. For Band 7, you have a range of occasionally-used structures with some flexibility – slight inaccuracies are tolerated in complex structures as long as it does not obscure the message. Your main takeaway is that even with some errors, complex structures do better than perfect simple sentence structure.

The most efficient way to learn grammatical range is by targeting specific areas that you want to focus on, rather than trying to learn all grammar rules. Find the advanced grammatical structures that you almost never use in your essays — by far the most common for band 6 candidates are passive voice, relative clauses and third conditionals — and then spend a week writing practice sentences with each one (one day = passive voice, another day = a relative clause… and so on). This kind of targeted practice will naturally blossom into essay settings all on their own, but it may take somewhere between two and three weeks of consistent work for those structures to appear without any conscious focus.

A practical rule for varying sentence structures in IELTS Task 2, is never write two of the same structures in a row. If your first sentence is a simple statement — subject-verb-object, the second must be complex — with heir relations or hypothesis For contrast and emphasis, if your first sentence is long and complex foremost, the second can follow with shorter and simpler. This change creates natural rhythm in your writing that is a sign of real grammatical ability to the examiner.

It is not only the grammatical range that makes complex sentences useful for your IELTS Task 2 but their capacity to express detailed ideas more efficiently. 'Technology has benefits. It also has drawbacks.' is two simple sentences. 'Despite its undeniable benefits to modern society, the advances of technology have also resulted in new social stratification which tends to impact more on lower socio economic community. is a more sophisticated, qualified thought expressed as a complex sentence — exactly what you would expect to earn task response band 7 for.

Conditionals is another the most powerful but also one of the least used grammar structures in IELTS Task 2. They enable you to write speculative assertions, make solutions with disclaimers, and recognize divergent situations — all of which help develop task response. They also show grammatical range because using the correct sequence of tense verb forms across an if-clause and result clause is essential. You can include one well-used conditional sentence for each essay, and that greatly influences your grammatical range score.

In IELTS Task 2, passive voice has two main functions: it demonstrates grammatical range (meaning that you can make passive constructions correctly) and formal register of your writing (usually written in academic topics because passive constructions occur more often than in spoken or informal English). The most natural contexts for using passive voice in IELTS essays: making general statements ('It is widely accepted that') reporting research or data ('Research has shown that') and writing about policies / measures ('Measures have been taken to').

The assessment of Grammar errors in IELTS are two-dimensional — both frequency and interference with meaning. Minor inaccuracies in complex structures (an omitted article, a wrong preposition) are not severely penalised when they do not prevent meaning from being understood — the examiner knows what you meant. Repeated errors of the most basic structural types (subject-verb agreement, very basic use of tenses) are punished more heavily, as they indicate a real breakdown in grammatical skill. Most band 6 candidates are focused on erasing recurrent basic mistakes, as opposed to filling fluency with complex sentences correctly every time.

The key phrase in the band score 7 grammar descriptor is 'rarely reduce communication' — if an error does not prevent the examiner understanding what you mean to say, then that error is permissible. Uniformity of the same type of mistake (dropping the article every time, having an incorrect subject-verb agreement form) indicates a systematic shortcoming and will exert a negative impact on writing score. The occasional other errors in convoluted structures should see efforts at range — which is rewarded by the criterion even if not properly achieved.

We are useful to use in IELTS Task 2 in this case, as well because relative clauses enable you to add qualifying detail and complexity without having to write separate sentences. 'Technology has transformed education. Technology broke the way through the hilly areas making learning resources open.' becomes, "The technology that has transformed practically every business of contemporary life has put high-quality learning materials into the hands of kids in parts of probably the farthest corners." You have something with relative clauses which is shorter, more elegant, higher level and offers a breadth of grammar in just one structure.

In fact, the only way you might realistically accomplish any variation in how a sentence begins is with an intentional editing step: when done writing each body paragraph, take a look at the first word of every sentence. When a number of consecutive sentences start with the same subject (eg Technology is…,' 'It has…,' 'This means…'), consider reformulating at least one sentence that starts differently. Use a mix of subject-first sentences, adverbial clause sentences ('Although this is true…'), and passive structures ('It has been argued that…') to show the structural variety which band 7 grammatical range is looking to reward.
