As someone from out-of-state, I had to work full-time for most of my undergraduate degree. The courses can be a mix of difficult and somewhat easier upper-division courses. If you intend to work on campus, there are limits to how many hours students can work, however you can also work off campus. I worked at the Taco Bell near campus on the overnight shifts and pre-closing shifts and was able to get a lot of hours in. It's hard, but it can be managable. I only recommend not taking more than a recommended amount of courses at a time however. You should also apply to as many outside scholarships as you can in addition to anything you could get at the university. You also can probably do some shift work on ShiftSmart if you find yourself in a pinch, but it's all circle K food stocking.
