Task Achievement / Task Response — Band 5.0

The response covers the main stages of the process, but the description is often unclear and lacks precision. While you identify the beginning and end, the explanation of the intermediate steps—such as the use of the straw, the glue, and the marking of the bottle—is confusing and fails to clearly communicate the mechanical process to the reader. The instructions are not fully developed, and the relationship between the steps is difficult to follow. To improve, focus on describing the sequence of actions more logically and ensuring that the purpose of each component (e.g., the straw, the hole, the markings) is explicitly stated.

Coherence and Cohesion — Band 5.0

The response is organized into paragraphs, but the progression of ideas is disjointed. While some cohesive devices are used, such as 'Firstly', 'Furthermore', and 'Afterwards', they are often applied incorrectly or do not effectively link the sentences. The internal logic of the sentences is frequently broken, making it difficult for the reader to follow the sequence of the process. For example, the transition between the water filling and the marking of the bottle is abrupt and lacks a clear logical connection. Improving the use of linking words and ensuring each sentence builds clearly upon the previous one is essential.

Lexical Resource — Band 5.0

The vocabulary is limited and often inaccurate, which hinders the clarity of the report. Phrases like 'timing things', 'full fill the bottle', and 'take away from hole' are non-standard and imprecise. There is a lack of technical or descriptive vocabulary appropriate for a process description. You rely on basic, repetitive language, and some word choices are confusing, such as 'delineates per minute of drops'. To reach a higher band, you should work on using more precise verbs and nouns related to technical processes and ensure that your collocations are natural and accurate.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that often impede communication. There are significant issues with subject-verb agreement (e.g., 'it has seven stage'), article usage, and sentence structure. Many sentences are fragmented or run-on, making them difficult to parse. For instance, 'when tap is on the water come across to cover hole' lacks necessary articles and correct verb forms. The range of structures is very limited, consisting mostly of simple, error-prone sentences. To improve, focus on mastering basic sentence construction, including correct verb tenses and the appropriate use of articles and prepositions.
