　　Nowadays, making money while in college is not really difficult. Many students can cover both their tuition and life expense without asking their parents for help. (22)One of their first options to make money in the area surrounding the university is a part-time job. That’s because most universities are located in areas that abound with retail stores, and therefore, retail jobs. These jobs always give college students a steady source of income. The universities’ work placement program can be helpful. Most universities offer these programs to help students gain employment that is easily accessible, ideal for a student’s schedule and flexible. (23) However, these jobs go quickly and may not offer as much of a Wag as other options. A less traditional way to make money is to get rid of all the extra things you aren’t using. (24) Try selling these items on the Internet. This option helps you clear some space in the apartment and at the same time, you get some extra income. The shortcoming is that you must pay a small percentage to the website for using the service. Babysitting may sound uninteresting. Yet it is a good choice of a part-time job for college students. There are lots of parents out there looking for quality and trustworthy people to mind their children while they go back to work. (25) It may provide you with additional study time during children’s nap time. All in all, finding suitable jobs depends on students’ skills and qualifications and their academic study should be the top priority.
