Writing Feedback / Task1: The number of hours spent in British University [2]

The proportion of undergraduates, postgraduates, and other students spending time in the library

The three pie charts illustrate how much time spent in a British university library of three kinds of students: undergraduates, postgraduates, and other students.
Overall, it is clear that the overwhelming majority of undergraduates and all students used library at least 7 hours, whereas the vast majority of postgraduates consumed over 15 hours at the library.

To be specific, the pattern for postgraduate students was substantially different. 51 percent of postgraduates spent fifteen hours or more in the library. This number is even higher than that of undergraduates and the entire student body combined. Furthermore, only 17 percent of post-graduation student spent less than 7 hours while the students who move towards graduation in this category is a hefty 63 percent.

Meanwhile, a relevant pattern was seen on range of eight to fourteen hours which postgraduates and the average students spent, capturing just 32 percent and 35 percent of the total. In addition, the proportion of postgraduate students who spent fifteen hours per week or more in the library was very close to all students who spent only 1-7 hours.
