IELTS Writing Correction
- 1. Describe the measured total Original: the Vietnamese telephone users grew Suggested revision: the number of telephone subscribers in Vietnam grew Why it matters: The chart tracks the number of subscriptions, not the physical growth of users.
- 2. Remove the extra words Original: throughout the in 2010 Suggested revision: throughout 2010 Why it matters: The phrase contains two unnecessary words that make the time expression ungrammatical.
- 3. Use concise chart language Original: As is presented in the diagram Suggested revision: As shown in the chart Why it matters: This concise reporting phrase is more natural for introducing chart details.
- 4. Add the count noun Original: total Vietnamese telephone customers Suggested revision: the total number of Vietnamese telephone subscribers Why it matters: A singular verb requires “the total number,” and “subscribers” matches the chart label.
- 5. Name the quantity Original: the subscription stood Suggested revision: the number of subscribers stood Why it matters: One subscription cannot represent the chart’s total number of subscribers.
- 6. Report the exact value Original: jumping over 144 million Suggested revision: rising to 144.4 million Why it matters: The October bar is labelled 144.4 million, and “rising” is suitably neutral.
- 7. Fix the time phrase Original: in October in this year Suggested revision: in October that year Why it matters: The repeated preposition makes the time expression awkward and unidiomatic.
- 8. Remove the preposition Original: reached to Suggested revision: reached Why it matters: “Reach” takes a direct object and is not followed by “to” here.

Why this response received Band 7.0
The response selects the main upward trend and the two temporary declines accurately, and it supports these points with well-chosen figures, including the largest monthly increase. The principal limitation is presentation in a single dense paragraph alongside several awkward or ungrammatical phrases. Divide the report into clear functional paragraphs and edit agreement, prepositions, and comparative structures to make the otherwise accurate account more polished.
IELTS Writing Criteria Scores
Task Achievement
The report accurately identifies the overall rise, both monthly declines, the endpoints, and the largest increase while selecting appropriate supporting data.
Add one or two intermediate figures from April to July to make the development across the whole year even more complete.
Coherence and Cohesion
The information follows a clear chronological progression and uses referencing effectively, but the single-paragraph presentation and long final sentence reduce readability.
Use separate introduction, overview, and detail paragraphs, and divide the final sentence into shorter linked points.
Lexical Resource
The vocabulary covers changes and quantities with reasonable variety, though collocations such as “users grew,” “progressively developed,” and “declined than” are imprecise.
Prefer accurate data-description collocations such as “subscriber numbers rose” and “declined from the preceding month.”
Grammatical Range and Accuracy
A mix of simple and complex forms communicates the data clearly, but agreement, preposition, article, and sentence-boundary errors recur.
Proofread specifically for subject-verb agreement, unnecessary prepositions after verbs, and run-on sentences.
