This chart is about the proportion of college students taking a part-time job. In grade one, the proportion is 25 percent. In grade two, the proportion increase to 30 percent. In grade three, the proportion is up to 35 percent. In grade four, the proportion is 38 percent, which still increases, but increases not so much. I guess, the reason may be that most students in grade four spend more time on finding a full-time job rather than taking a part-time job. I think, the proportion of college students taking a part-time job is too high. The most important thing for students is study. Why does so many students have to take a part-time job? The school fee is too high? If so, colleges must do something to change that situation.
