Task Achievement / Task Response — Band 6.5

The response addresses the prompt by taking a clear position and providing relevant arguments. You focus on healthcare and public infrastructure as key areas where science should intervene. However, the development of these ideas is somewhat limited. For instance, the discussion on traffic and environmental issues is a bit rushed, and the link between these problems and the 'improvement of lives' could be more explicitly articulated. To reach a higher band, ensure that each paragraph fully explores the 'why' and 'how' of your arguments, providing more depth rather than listing multiple issues. Your position is consistent throughout the essay.

Coherence and Cohesion — Band 6.5

The essay is organized into logical paragraphs, each with a clear focus. You use basic cohesive devices such as 'Firstly', 'Secondly', 'For instance', and 'Therefore' to guide the reader. However, the flow between sentences is sometimes mechanical, and the transition between the discussion of medical issues and public infrastructure is abrupt. To improve, try to use a wider variety of linking words and ensure that the relationship between ideas is more fluid. The paragraphing is appropriate, but the concluding paragraph is quite brief and could better summarize the main points to provide a stronger sense of closure.

Lexical Resource — Band 6.5

You demonstrate an adequate range of vocabulary for the task, using terms like 'mitigate', 'innovations', 'irreversible damage', and 'aquatic animals'. However, there are some inaccuracies in word choice and collocation, such as 'do inventions' (instead of 'make inventions') and 'permanent medical of solution' (which is grammatically awkward). There is also some repetition of basic words. To achieve a higher score, focus on using more precise collocations and avoiding word-choice errors. Expanding your range to include more academic or topic-specific vocabulary would also be beneficial for a higher band.

Grammatical Range and Accuracy — Band 6.0

The essay contains a mix of simple and complex sentence structures. While you attempt complex sentences, there are frequent errors in grammar and punctuation that occasionally hinder the flow. Examples include 'I am strongly agree' (should be 'I strongly agree'), 'I have to saw him' (should be 'I have seen him'), and 'it necessary that' (missing 'is'). Additionally, there are issues with article usage and subject-verb agreement. While these errors do not completely impede communication, they are frequent enough to prevent a higher score. Focus on proofreading for basic grammatical accuracy and subject-verb consistency.
