Nursing student making it on her own

Hi everyone! I'm new to this whole thing, I love coming here and reading through the forums; they're so helpful!

I just started my first semester of college this past month, and wow, is all I have to say.
I'm considered 'Pre-Nursing' right now, I'm going for BSN.
I've completed my CNA training, and I just got my ATT today in the mail to go take my state test (Michigan). I had a couple questions about the whole CNA job and living on my own. Where I want to be employed (they start off at about $12 an hour) is it possible to work a 30 maybe even 40 hour week to afford an apartment?
The one I've been looking at is about $500 a month plus utilities. HELP! I just need a peace of mind as to whether it's possible to be moved out on my own with a CNA job plus being a full time nursing student.
