The charts below give information about the number of hours that students study each day

The given chart revealed the details about the average number of hours students spend for education at five separate universities.
In general, the study times of students on weekdays are outweighed compared to this figure on weekends. Furthermore, students in University D spend less time studying for a whole week, compared to other universities.
In terms of studying time on weekdays, the hours which students study at university A and university D are recorded at 9,6 and 9,8, respectively. Undergraduate students in University C are the most dedicated for studying, with 10,6 hours on weekdays, then followed by the university E and university B which this figure ranges from 10 to 10,1 hours.
On weekends, while students in university A spend most time on course , about 9%, this figure for university D is around 5,6 which is the least compared to others. The time of students in university B which is spent taking part in the course was recorded at 8,6 hours. The figures for university E and university C on weekends are reckoned to be 6,2 hours for the former and 7,8 hours for the latter.

The summary overview is missing important reference information that has made it very difficult for me to understand the rest of the information presentation. You need to provide a more comprehensive listing of summary information such as:

1. The location of the universities
2. The letter assignments of the universities
3. How the measurements were completed (value reference)

You can add any information that you feel is pivotal to the presentation in this case. Just to help the reader get a clearer view of what information is presented and how. Remember, when you are not cohesive and coherent in the presentation, you will find that you will receive either a low or failing score in that section. It is the clarity that proves to be the main problem in this reference essay.
