You will find out for yourself how much work your course work will be for you, and how much time you will have for a part-time job. Some students have plenty of time left over to work for pay, while others may have a harder time fitting course work and working for pay into their schedule.
Your first priority should be your course work. If working for pay during college is optional in terms of affording college, do so only if it will not cause you to do poorly in your course work (the worst case is failing courses and having to take an expensive extra semester to graduate).
You may want to consider some jobs that may be helpful to your academics. For example, working as a tutor in the tutoring center, or other academic support jobs, may help you reinforce your knowledge. Some other jobs may be helpful to exploring your career options (e.g. working in an engineering lab, or writing computer software).
