📝 Sample Task with Strong Model Answer

Question: The bar chart below shows the number of international students enrolled in science and engineering programs at three universities in 2020. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Sample Answer:

Introduction:
The bar chart presents data on the number of international students enrolled in science and engineering courses at University A, University B, and University C in the year 2020. The figures are given in thousands.

Overview:
Overall, University C had the highest international enrollment across both fields, while University B attracted the fewest students. Engineering consistently had higher enrollment numbers than science at all three institutions.

Body Paragraph 1:
At University C, international enrollment in engineering programs reached just over 18,000 students, the highest single figure on the chart. The number of science students at the same institution was also high, at approximately 14,000. These numbers were significantly higher than those recorded at the other two universities. University A followed, with around 12,000 engineering students and 9,000 in science.

Body Paragraph 2:
In contrast, University B had noticeably lower enrollment numbers. Fewer than 8,000 international students enrolled in engineering, and only 5,000 chose science. Despite the differences in scale, all three universities showed a consistent pattern: more international students preferred engineering over science. The gap between engineering and science was also greatest at University B, where nearly 3,000 more students enrolled in engineering.
