Detailed IELTS Data Analysis Example
Sample Task Prompt (Bar Chart)
“The chart shows the number of international students in five different countries in 2025 and 2026. Summarize the main information by selecting and reporting the significant features, and make comparisons where relevant.”
Step-by-step Data Analysis:
