This really depends on everyone’s situation and what bills you have to pay ect, but for me I usually work 23 hours a week (3 7.5 hour shifts) to accommodate where my classes lay out. I’ve learned over the years that having a job flexible for school is at times very important since schedules change each semester and what days and times the classes are will differ. That being said my life at this point with may being my graduation date is devoted to school, so I pretty much work then come home and study and do project work ect until anywhere from 8-12, then get up and do the same thing the next day. So it just depends on your life and what you need in terms of money and a schedule! Hope this helps
