Is it better for college students to work full time or part time? Please vote and answer

I start back school next month and I know that I’m needed full time at the preschool job. I work from 7am to 3pm. I’m thinking about working from 7am or 12 or 1pm. It may not work because of the schedule but they say they may be able to work something out. I don’t know. What do you guys think?
