What should I do? Just skip the class?

Fresh out of high school, I planned on going to a career center for 3 months to be certified to be a pharmacy technician, then in january to go to a university for a real career. I won a $500 scholarship to go to the career center with, but have to pay $1200 out of my pocket or get a loan, and the classes might last until january when i want to start my university classes, so they might overlap (not sure when classes start, whenever they get enough people is what they told me). So do you think its worth the extra time, energy, money, and the fact it might overlap with my university work, to have a job while in college?
