Are these work hours ok for when I start college?

I'm starting college this fall. Obviously I'll just be starting my generals. I'm going for my LPN then taking an RN mobility program. But I do want to finish my generals and LPN courses as soon as possible to start on my RN. I work at JCPenney right now as night crew (10pm-4am.) I took this job just for the experience. I've been here for about 4 months I believe. But right when I'm supposed to start school, the hours are changing to 6am-12pm 3 days a week. If I want to dedicate a lot of my time to school, will these hours work for me? I heard you should take the minimal credits to be considered a full time student so you don't stress yourself out. So what do you think? A. Keep my job and take it easy on the credits so I don't burn myself out on school B. Quite my job in a few months when school starts and dedicate most of my time to school. I'm completely stuck on this decision. The people I work with has really grown on me but school is so much more important. The pay isn't good but like I said, I took the job for the work experience. Any advice would help me out a bunch. Thanks!
