Overall assessment

Why this response received Band 7.0

The strongest aspect is the clear, well-organised reporting of the three metals' monthly price changes with a relevant overview and mostly accurate data selection. The main limitation is the occasional inaccuracy, including the claim that December's zinc figure was the highest point of the year despite nickel's 6% rise in January, alongside some imprecise wording.

IELTS criteria

How each score was decided

Task Achievement

6.5

The response covers the key trends across the year with a clear overview and largely accurate data, but the unsupported claim that zinc's 2% December rise was the highest point of the year conflicts with nickel's 6% January figure and the slightly imprecise description of zinc's mid-year values limit achievement.

Coherence and Cohesion

7.0

The information is logically sequenced across three clear paragraphs with a logical half-year division, and a range of cohesive devices is used naturally without overuse.

Lexical Resource

7.0

The vocabulary is sufficiently flexible for the task, using terms like 'fluctuations', 'dramatic', 'decline', and 'surge' appropriately, with only minor imprecision such as 'minerals' instead of metals and some reliance on trend verbs.

Grammatical Range and Accuracy

7.0

A variety of complex and simple structures is used with good control, including comparative clauses and time references, and errors are rare and non-impeding.
