I tutored students when i was in college, during the entire academic year. It was great extra money (at least for a student

). I gave both mathematics and physics to freshmen-students and high school students. The took place in a private organization and involved planning a working schedule, meeting with partents/ other teachers (most of them also students) and ofcourse giving physics and mathematics. It was a great experience, especially because i learned a lot from it. I mean, there is a big difference between being able to complete a good physics exam and being able to teach physics in front of students and solve problems at the instant.
Trust me, try to find such a job, it is really good for several reasons (money, experience, learning and relaxing...). Just be sure that when you do a job while being at college, you need to have a strick planning that you must respect. Also, try to find a job that is closely related to what you study. In that case, outside teaching, there is not going to be very much.
