Among college students, there are not a few students who do part-time jobs. I have many part-time jobs around me, and I can earn 1800 a month. There is no need to ask the family for living expenses every month. For example, cooking in the canteen, distributing leaflets, driving school and other part-time jobs are all hard part-time jobs. If you can study hard, you can also go to some educational institutions as a substitute tutor. These part-time jobs are well paid, but college students must keep their eyes open when looking for part-time jobs. There are many immoral and dark businesses in the society, deceiving college students and finding part-time jobs must take professional and formal channels. I think the best opportunity to make money is to do research with teachers, make my own works and apply for patents. This is the most cost-effective, and you can learn knowledge. Why not? Be sure to share your part-time job with your roommates, and let them refer to whether it is irregular or unreasonable. Roommates are also friends who have the most contact at school besides family members.
