Task Achievement / Task Response — Band 4.0
The response fails to meet the minimum word count requirement of 150 words, stopping abruptly at only 138 words. Furthermore, the student only describes a small portion of the first diagram and does not even complete the description of the map from 20 years ago, completely omitting the second map of the library today apart from a brief introductory sentence. There is no overall summary or comparison attempted for the library's evolution. According to the band descriptors, because the task is significantly truncated and incomplete, it falls under Band 4.0 as it addresses the task only minimally and lacks development.
Coherence and Cohesion — Band 4.0
The text is heavily fragmented with severe organizational issues. The student attempts to structure the essay into paragraphs, but the second map's description is cut off after a single introductory sentence, and the body paragraphs lack logical progression. Cohesive devices are minimal and mechanical (e.g., repeating 'The first diagram', 'The second diagram'), and referencing is faulty. Paragraphing is inappropriate due to the incomplete nature of the response. This performance aligns with Band 4 descriptors, where information and ideas are not arranged coherently throughout.
Lexical Resource — Band 4.0
The vocabulary used is basic and repetitive, with frequent spelling mistakes such as 'demonstartes', 'tabels', 'vedios', 'childern's', and 'paln'. The student relies heavily on basic terms like 'rooms', 'desk', and 'portion' without demonstrating the lexical flexibility required for Academic Task 1 (such as verbs of change or precise spatial vocabulary). Word choice is limited and strain the reader at times due to spelling and collocation errors. These features fit the Band 4 descriptor for lexical resource.
Grammatical Range and Accuracy — Band 4.0
Grammatical control is weak throughout the brief text. There are numerous basic errors, such as subject-verb agreement issues ('there had two tabels', 'There is two portions', 'There are one desk'), tense confusion ('20 year ago that there had'), and awkward phrasing ('how its look now'). Simple sentence structures dominate, and attempts at more complex constructions result in severe ungrammaticality. Punctuation and article usage are also problematic. This reflects a Band 4 level of grammatical accuracy.
