In IELTS Writing Task 1, topics that involve multiple types of graph are often called combined charts or mixed charts. For example, the topic may contain a bar chart and a pie chart.
Please keep in mind the following points when you face this question type:
- Normally, there are two graphs only, such as a line graph and a table, because of the limitation of time allowance.
- Each graph tends to be less detailed and complex than when it is given as the only graph.
- You should manage time well. For example, if there are two different graphs, then try to spend at most 10 minutes describing each graph.
A sample topic containing two graphs: a bar chart and a pie chart, followed by a sample essay:
The bar chart demonstrates the reasons why adults decide to study, whereas the pie chart shows people’s opinions on how the costs of adult education should be financed.
40% of survey participants believe that it is the individuals who should be responsible for the costs of their study. 35% and 25% of respondents take a different view and think that employers and taxpayers, respectively, should help fund the costs of adult education.
Of the eight reasons why adults decide to take a course, having an academic interest leads the way with a record of 40%, followed by gaining qualifications with 38%. 22% of adults learn as a way to support their current job, whereas improving promotion opportunities and enjoying the study are the motives that push 40% of adults, in total, to pursue a course.
The proportions for being able to change jobs and meet people are the lowest. Only 12% of survey participants choose a course because of the former reason and only 9% decide to study to get chances to know new people.
