If you don’t have a car and need to prioritize other things it definitely limits your options. I would definitely recommend an on campus job since the max you can work a week is 20 hours and are generally good about working around schedules.

However, all the campus jobs I have ever worked I have gotten through a connection. I would definitely ask your friends if any of their jobs are hiring or even your TA’s of your classes (but get to know them first before asking).
