IELTS Writing Task 1 question
The graph below shows the average monthly change in the prices of three metals during 2014.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Average monthly change in prices of copper, nickel and zinc (2014)
Student answer (Band 7.0)
The line graph illustrates the monthly transitions in the prices of three metals- Copper, Nickel, and Zinc- on an average in the year 2014.
Overall, it is clear that nickel was the only metal that had the highest proportion in charges in the beginning of the year, and later in the end of the trend it was lowest among all 3. Whereas, zinc accounted for the lowest percentage in the starting of the year, which later ranked highest in the end of the period.
Looking at information in detail, in January 2014, nickel recorded the highest proportion in the price (6%) which later fluctuated before falling drastically to -3% in June. Later the figure rose gradually to -1% in July and stayed constant. Finally, in the last second month the figures rose dramatically to 1% and remained stable till December.
On the other hand, zinc accounted for the lowest percentage in charges (1%) in January, which later fluctuated through out the trend and ranked the highest in the end of the year 2014 (2%). However, Copper had 2% charges in first moth of the year which fluctuated throughout the year but had figures slightly below 2% in December

Task Achievement / Task Response — Band 7.0
The response covers all parts of the task by identifying the main trends for the three metals. You successfully highlighted the key features, such as Nickel's initial peak and subsequent decline, and Zinc's rise to the highest point. However, the analysis is slightly hindered by some inaccuracies in data interpretation; for instance, describing the figures as 'proportions' or 'percentages' is technically incorrect as the graph shows 'average monthly change' in prices. Additionally, the description of the trends could be more precise by focusing on the specific months where significant changes occurred rather than using vague time markers like 'last second month'. Overall, the report is clear and provides a good summary of the main features.
Coherence and Cohesion — Band 7.0
The response is logically organized with a clear introduction, an overview, and two body paragraphs. The progression of ideas is generally easy to follow. You used some cohesive devices such as 'Whereas', 'Looking at information in detail', and 'On the other hand' to link your points. However, some transitions feel a bit mechanical, and the referencing could be smoother. For example, the final sentence regarding Copper is somewhat abrupt and lacks a clear connection to the preceding analysis of Zinc. Improving the variety of linking words and ensuring each paragraph has a clear focus would enhance the overall flow.
Lexical Resource — Band 6.5
You demonstrate an adequate range of vocabulary for the task, using terms like 'fluctuated', 'drastically', and 'remained stable'. However, there are some issues with word choice and collocation. Referring to price changes as 'proportions' or 'charges' is imprecise in this context. Additionally, there are minor spelling errors such as 'moth' instead of 'month' and 'through out' instead of 'throughout'. To reach a higher band, focus on using more precise terminology related to data description, such as 'volatility', 'marginal', or 'upward trajectory', and ensure that your vocabulary choices accurately reflect the data presented in the graph.
Grammatical Range and Accuracy — Band 6.5
The response uses a mix of simple and complex sentence structures. While the meaning is generally clear, there are several grammatical slips. For example, 'in the last second month' is awkward phrasing, and 'in first moth of the year' is missing an article. There are also minor punctuation issues, such as the inconsistent use of hyphens and commas. While these errors do not impede communication, they occur frequently enough to prevent a higher score. To improve, focus on subject-verb agreement, correct article usage, and ensuring that complex sentences are constructed with greater accuracy.
