Band 6+: The pie charts below show the different types of courses, which were followed by the students during the years of 1984, 1994 and 2004. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The corrolation datas give information about the percentage of pupil whose enrollment in different types of courses in selected years.

In contrast, the majority of the students enrolled in the face-to-face courses by 67% that is three times more than correspondence one in 1984, while a mixed media is considered the lowest percentage by 13%. One more important thing is that although the proportion of learners taking correspondence courses is remained unchanged by 1 out of 5, it is still less than double face-to-face one in 1994. Another main point is that online lectures are emerged in this period just over 10% of pupils which is almost the same as mixed media one. Another significant feature is that after one decade, the rate of mixed media directions is reached by 35%, nearly equaling the face-to-face that is about 3 times more than online one.

Finally, these charts are highlighted significant changes over the two decades, with a steady decrease in traditional courses also a rise in mixed media and online.
