The question
The graph shows the weekly sales, in thousands of units, of three products over a six-week period.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.
What to notice before you write
The lines show different trends: A and C go up, B goes down. A and B cross at week 3 (both at 30). C stays lowest but rises in the second half. Open with the overall contrast, then describe the products with opposite trends separately.
Band 7 sample report
The line graph shows how many units of three different products were sold each week over six weeks.
Overall, sales of Products A and C rose over the period, whereas sales of Product B fell. Product A ended as the best-selling product, overtaking Product B from the fourth week.
Product A started at 20 thousand units and grew steadily to 40 thousand by week 6, despite a slight dip to 28 thousand in week 4. In contrast, Product B began as the market leader at 35 thousand units but declined every week, reaching only 18 thousand at the end.
Product C had the lowest sales at the start, at 15 thousand units, and the figure stayed unchanged in week 2. It then increased from week 3 onwards and climbed to 30 thousand by the final week, doubling its starting level.
By the end of the period, the order of the products had completely reversed: Product A was first with 40 thousand units, Product C second with 30 thousand, and Product B had fallen to last place with 18 thousand.
