Look at the following bar charts, taken from Cambridge IELTS 3, page 73.
The charts below show the levels of participation in education and science in developing and industrialised countries in 1980 and 1990.
You must give an overview of the information. This means that you need to find an overall trend that connects all 3 charts.
Can you find any overall trends? Feel free to discuss your ideas in the "comments" area. I'll tell you what I think tomorrow.
