Task Achievement / Task Response — Band 5.0

The response attempts to describe the process of making a water clock across seven stages, starting from turning on the tap and concluding with timing things. While the main steps are mentioned, the explanation lacks clarity and precision in connecting the physical components (such as the straw, the overflow, and the calibration lines) to their functions. The opening sentence is grammatically incomplete ('The diagram shows that the process stages for developing a water clock.'), and important details from the visual—such as the marking of horizontal calibration lines on the lower bottle—are omitted or poorly explained. Because the information is presented in a somewhat disjointed manner, it addresses the task only partially, aligning with Band 5.

Coherence and Cohesion — Band 5.0

The text is organized into four brief paragraphs, but the overall progression of ideas is hindered by a lack of proper punctuation and cohesive devices. The response suffers from run-on sentences, such as the lengthy middle paragraph ('Intially, on the fucet and store the water in to plastic bottle...'). Cohesive devices are either missing or misused ('Furthermore and place another bottle...'), and referencing between the steps is frequently unclear. Paragraphing is attempted, but the internal cohesion within paragraphs is weak, making it difficult for the reader to follow the sequence smoothly. This places the performance firmly in the Band 5 category.

Lexical Resource — Band 5.0

The vocabulary used is quite basic and repetitive, with several spelling errors ('fucet' for faucet, 'Intially' initially, 'timming' timing, 'mantain' maintain). There are also frequent issues with word choice and collocation, such as 'consist on' instead of 'consists of' and 'tap on' instead of 'turn on the tap'. While the writer attempts some process-related terminology like 'sequential stages' and 'constant', the range of vocabulary is limited and noticeable errors occasionally cause difficulty for the reader, fitting the descriptors for Band 5.

Grammatical Range and Accuracy — Band 4.0

The grammatical range is severely limited, consisting mostly of poorly constructed simple sentences and faulty attempts at complex structures. There is a complete lack of proper sentence boundaries, resulting in comma splices and run-on sentences joined by conjunctions without punctuation (e.g., 'when bottle fill with the water then water over flow in the straw because it mantain the water level constant'). Errors in tense, preposition usage ('in to plastic bottle'), and article omission are frequent and impede readability. This demonstrates control characteristic of Band 4.
