Task Achievement / Task Response — Band 4.0

The response is significantly under the 150-word minimum requirement, which severely impacts the task achievement score. Because the text is incomplete and cuts off mid-sentence, it fails to describe the full process shown in the diagram. While the introduction and overview attempt to address the task, the lack of development and the failure to complete the description of the seven stages mean that the requirements of the prompt have not been met. To improve, you must ensure you complete the entire description and meet the minimum word count by providing sufficient detail for each step of the process.

Coherence and Cohesion — Band 5.0

The response shows a basic attempt at logical organization with an introduction and an overview. However, because the text is incomplete, the progression of ideas is interrupted. Cohesive devices such as 'First and the foremost' are used, but the overall structure is undermined by the abrupt ending. To improve, ensure that your response is complete and that you use a wider variety of cohesive devices to link the stages of the process more fluidly, ensuring that the transition between steps is clear and logical for the reader.

Lexical Resource — Band 5.0

The vocabulary used is generally adequate for the task, with terms like 'graduated container' and 'passage of time' being appropriate for a process description. However, there are some errors in word choice and phrasing, such as 'building a own water clock' and 'on the water tap into plastic bottle'. The range is limited due to the brevity of the response. To achieve a higher band, focus on using more precise technical vocabulary related to the diagram and ensure your word choices are grammatically accurate within the context of the sentence.

Grammatical Range and Accuracy — Band 5.0

The response contains several grammatical errors, such as 'illustrates process of building a own water clock' (missing articles) and 'in a particular stages which define' (subject-verb agreement and preposition errors). The sentence structures are relatively simple, and the incomplete nature of the text prevents the demonstration of a wider range of complex structures. To improve, focus on mastering basic sentence construction, including the correct use of articles, prepositions, and verb tenses, and aim to incorporate more complex sentence structures once your foundational grammar is more consistent.
