Task Achievement / Task Response — Band 5.0

The response covers the main stages of the process, but it fails to meet the minimum word count requirement of 150 words, which significantly impacts the score. While the key steps are identified, the description is somewhat brief and lacks the necessary detail to fully explain the mechanism. The introduction is slightly awkward, and the conclusion is missing. To improve, you should expand on the physical interaction between the components, such as the role of the straw and the specific function of the overflow mechanism, to ensure a more comprehensive overview of the process.

Coherence and Cohesion — Band 5.5

The essay is organized into short paragraphs, which helps the reader follow the sequence of events. However, the use of cohesive devices is often mechanical or inaccurate, such as 'while, which begin with' and 'Moving further, On reaching'. These transitions do not flow naturally. The referencing is sometimes unclear, particularly when referring to the bottles. To achieve a higher band, you should focus on using a wider variety of linking words and ensuring that each sentence connects logically to the previous one without relying on repetitive structures.

Lexical Resource — Band 5.5

The vocabulary is generally adequate for the task but lacks the precision required for a higher band. There are several instances of awkward phrasing, such as 'making and functioned of water clock' and 'water allowed overflow of though the straw'. These errors indicate a limited control over word choice and collocation. To improve, you should aim to use more precise technical vocabulary related to processes and mechanisms, and ensure that your word forms (e.g., 'functioned' vs 'functioning') are used correctly in context.

Grammatical Range and Accuracy — Band 5.0

Examples include 'illustrates that how to build', 'The process begin with functioning', and 'water allowed overflow of though the straw'. There is a lack of complex sentence structures, and the existing sentences often contain errors in subject-verb agreement and preposition usage. To improve, you should focus on mastering basic sentence construction and ensuring that your verb tenses are consistent throughout the report. Proofreading for simple errors like missing articles or incorrect verb forms is essential.
