Task Achievement / Task Response — Band 6.5

The response addresses both parts of the prompt: the problems caused by lack of sleep and potential solutions. The ideas are relevant, such as poor mental performance and the impact of technology, and they are supported with examples like university students and employees. However, the development is somewhat basic. For instance, the discussion on health problems is a list of conditions (obesity, high blood pressure) without further elaboration on how sleep deprivation leads to these specific outcomes. To reach a higher band, you should expand on the 'why' and 'how' behind your points rather than just listing them. Overall, the position is clear and the response is well-structured for the task.

Coherence and Cohesion — Band 7.0

The essay is logically organized into clear paragraphs, each with a distinct focus. You use cohesive devices such as 'One major problem', 'Additionally', 'On the other hand', and 'To put it in a nutshell' to guide the reader. However, some transitions are slightly mechanical or repetitive, such as the frequent use of 'there are several ways in which'. The referencing is generally clear, though the concluding sentence is a bit clunky due to the redundant use of 'however' after 'although'. Improving the variety of your linking words and ensuring smoother transitions between sentences would enhance the flow.

Lexical Resource — Band 6.0

You demonstrate an adequate range of vocabulary for the task, using terms like 'hectic schedule', 'sufficiently', and 'consumption'. There are some minor inaccuracies in word choice and collocation, such as 'get cure' (should be 'find a cure' or 'remedy the situation') and 'contribute for reducing' (should be 'contribute to reducing'). While you attempt to use more sophisticated vocabulary, some phrasing remains slightly simplistic. To improve, focus on using more precise collocations and avoiding repetitive phrasing. The vocabulary is sufficient to convey your meaning clearly throughout the essay.

Grammatical Range and Accuracy — Band 6.0

The essay uses a mix of simple and complex sentence structures. While you successfully use some complex sentences, there are frequent grammatical errors, particularly with subject-verb agreement (e.g., 'a university student who do not sleep', 'having less sleep create') and article usage. Additionally, there are minor punctuation issues, such as the unnecessary comma after 'like' in the first paragraph. While these errors do not impede communication, they are persistent enough to prevent a higher score. Focusing on proofreading for subject-verb agreement and ensuring consistent verb tense usage will significantly improve your accuracy.
