Should I work?

Ok, two questions. 1- Last semester I worked at my college for about 10 hours a week. This semester I only go to college 2 days a week (from 8am-3pm) and have 4 hours of free time a week (12-2) I need to eat lunch during that time and it would be nice to have a break to hang out with my friends after 3 classes, or study. I don’t know if I should go back to that job or just forget about a campus job this semester. By the way, it’s minimum wage. 2- I don’t know if I should get a job while I’m at home (5 days a week). I don’t really NEED any money since I live with my parents this semester. I don’t drive yet and I’ve only had one other job (the campus job). Also, when I applied for the campus job they never asked for my working papers.. (I’m 17). I don’t know if those take long to get or not. I’m trying to raise my GPA up and I have been using the time I have to study. However I DO enjoy having money :D I might want to save up for a car once I get that license. Advice?
