I am getting very little hours and will be going back to college soon, should I look for another job?

Right now I am only getting random hours a week. It is a retail position however, I do not like the fact that I am getting very little hours. I always come in on time and I know it is retail but 5 hours last week and only 10 this week? I will be going back to college in the fall and was wondering if I should try to get a job in the mean time that has a more consistent schedule and that could give me at least 15 hours a week as I make barely above minimum wage. I don't know what to do because it seems like that this is something that can continue and when I go back to school, I can't work these same odd ball hours again, so should I try to find a job better around my schedule, or should I just stick it out there and see where it goes.
