Grammatical Range and Accuracy evaluate the variety and correctness of sentence structures. This includes both the complexity of the sentences and the precision of grammatical forms.

Key Aspects:

• Range of Structures: Candidates should demonstrate the ability to use a variety of sentence structures, including simple, compound, and complex sentences. The use of conditionals, passive voice, and relative clauses adds variety and sophistication to the writing.
• Accuracy: Correct use of grammar is essential, including tense consistency, subject-verb agreement, articles, prepositions, and punctuation. Grammatical errors can hinder understanding and reduce the overall score.
• Complex Sentences: Using a mix of sentence types (simple, compound, and complex) helps show the candidate’s ability to present ideas in a sophisticated manner. For example, “Although public transport is convenient, it may not be feasible to make it free due to high operational costs.” This sentence combines clauses to express a nuanced argument.
• Error-Free Sentences: The number of mistakes should be minimal, and sentences should be clear and easy to understand.

Example:

A candidate discussing pollution might write: 

“While air pollution has decreased in many urban areas, primarily due to stricter environmental regulations, water pollution remains a significant concern, particularly in developing countries.” 

This sentence uses a complex structure with accurate grammar, demonstrating both variety and control.
