Hmmmm ... saving up for an apartment? Can you do that?
An apartment is an ongoing expense ... it would seem you would need enough income to cover the rent, utilities, etc. Is this possible? If not, why not?
From my own experience it's a shock going off your parents' payroll (assuming you're on it to begin with). My first year in graduate school was a lesson in this. I had about $60 every two weeks left over after paying for my room. I hadn't eaten yet! So those two semesters I dipped into savings. Oh, by the way, I didn't have a car.
My shoot-from-the-hip advice would be to hold off on the apartment until you have the income. But again, not knowing the specifics, YMMV.
