Student answer (Band 7.0)

In recent years, a significant amount of people hav reported that they have difficulty getting adequate sleep. This essay will discuss the major problems caused by sleep deprivation and suggest practical measures to address them.

In this fast-paced world, a large number of people have difficulty getting proper sleep hours. This habit can result in lower productivity in students and adults at school or at work. This lack of sleep often manifests itself as a lack of motivation in human behaviour. Moreover, the chances of making more mistakes increase, which can make adults vulnerable in their workplaces. For instance, a driver of a company, if not well-rested, can fall asleep while driving on the road, which may lead to an accident. So, not only does lack of sleep negatively impact on humans and their productivity, but it can also become an indirect cause of financial loss for a business.

However, by adopting small healthy habits on a daily basis, one can gradually improve the sleep cycle. Scientific evidence says that a hormone named melatonin, which helps one fall asleep, is released in the human body after sunset, so sleeping early at night can be a crucial step to improving the sleep cycle. Another contributing factor that can help one get adequate sleep is not using screens three hours before going to bed. Additionally, caffeine intake can also interfere with the part of the brain that promotes sleep. So, avoiding it, especially late at night, can be an ultimate positive step.

In conclusion, in this modern era, a substantial number of people complain about not having sufficient sleep. On the one hand, lack of productivity and financial loss for a business can be the outcomes of it; the solutions can be the small steps that a person can take, such as avoiding caffeine and screens late at night and going to bed early at night.

AI examiner evaluation

Task Achievement / Task Response — Band 5.5

The response is completely off-topic. The prompt explicitly asks about the environmental damage caused by plastic and solutions to address that specific issue. However, the student has written an entire essay about sleep deprivation. Because the response fails to address any part of the actual task question, it cannot be assessed for task achievement in relation to the prompt provided. In an official IELTS examination, this would result in a very low score for Task Response as the content is entirely irrelevant to the instructions given.

Coherence and Cohesion — Band 7.5

Despite the content being irrelevant to the prompt, the essay itself is internally coherent. The student uses clear paragraphing and logical progression. Cohesive devices such as 'Moreover', 'For instance', 'However', and 'In conclusion' are used effectively to link ideas. The structure follows a standard essay format with an introduction, body paragraphs, and a conclusion. If the content had matched the prompt, this would be a strong performance in terms of organization and flow.

Lexical Resource — Band 7.5

The vocabulary is generally appropriate and demonstrates a good range. The student uses terms like 'fast-paced world', 'manifests itself', 'vulnerable', and 'interfere with' correctly. There is an attempt to use more sophisticated language, and the word choice is natural and precise throughout the text. While the topic is incorrect, the lexical control displayed is quite high, showing an ability to express complex ideas clearly.

Grammatical Range and Accuracy — Band 7.5

The student demonstrates a good command of grammatical structures. There is a mix of simple and complex sentences, such as 'Not only does lack of sleep negatively impact on humans... but it can also become an indirect cause of financial loss'. Punctuation is generally accurate, and errors are very rare. The control over verb tenses and subject-verb agreement is consistent, indicating a high level of grammatical competence.
