Task Achievement / Task Response — Band 5.5
The response addresses the prompt and maintains a clear position throughout. The ideas are relevant, focusing on healthcare and education as primary areas where science improves lives. However, the development of these ideas is somewhat limited. For instance, the example regarding cancer diagnosis is vague, and the connection between renewable energy and the prompt's core argument could be more explicitly linked to the 'improvement of lives.' While the position is clear, the supporting arguments lack the depth required for a higher band, often relying on general statements rather than fully extended analysis.
Coherence and Cohesion — Band 5.5
The essay is organized into logical paragraphs, with an introduction, two body paragraphs, and a conclusion. Cohesive devices such as 'To begin with,' 'Firstly,' 'In addition,' and 'In conclusion' are used to guide the reader. However, the flow within paragraphs is sometimes mechanical, and there are instances where the progression of ideas feels slightly disjointed, such as the sudden transition to renewable energy in the second body paragraph. Referencing is generally clear, but the overall structure could benefit from more sophisticated linking between sentences to improve the flow.
Lexical Resource — Band 5.5
The vocabulary is adequate for the task, allowing the student to convey their meaning clearly. There are attempts to use topic-specific vocabulary like 'scientific discoveries,' 'technological innovations,' and 'renewable energy.' However, there are several instances of awkward word choice and collocation errors, such as 'In recent year' (should be 'years'), 'human live' (should be 'lives'), and 'advance in academic' (should be 'advancements in academia'). The range is sufficient to communicate, but the lack of precision and occasional errors in word formation limit the score.
Grammatical Range and Accuracy — Band 5.5
The essay uses a mix of simple and complex sentence structures. While the student attempts complex sentences, there are frequent grammatical errors that occur throughout the text. Examples include subject-verb agreement issues ('science is help,' 'it contribute'), incorrect article usage, and tense inconsistencies ('Some people argued'). While these errors do not typically impede communication, they are frequent enough to demonstrate a lack of control over more complex structures. Punctuation is generally functional, but the sentence construction often feels repetitive or slightly unnatural due to the grammatical slips.
