Job situation help about nursing??

I am currently a full time college student and I also have a full time job and a part time job. (I take two online classes and take the other two MWF so I don't have to go to the campus everyday) I do admit that working everyday has taken a toll on my grades. They are not as good as I would like, but I'm still maintatining my grades to keep my scholarship.

Anyway, I currently work at a cell phone store and a clothing department store but I am going to school to become a nurse (*maybe* a doctor in the far future but that's not my top priority right now). There is a rehabilitation center right in the area where my other two jobs are located. Is it possible for me to get a job there with only a high school diploma as my highest form of education at the moment? If so what are some things I would be doing there? I am wondering this because it relates to the field I want to go into so I think the experience would help(I do not plan on staying w/ cell phones, etc after college)

I am not sure if "rehabilitation center" means a large rehab hospital or a small clinic offering physical therapy. If it is the former, you might be able to work as a unit secretary or a transporter.

Do you have your nursing assistant certification? That is an easy few week course you can take and would help you get a nursing related job. (Plus with clinicals, being a CNA will help SO MUCH!)
They MAY be able to hire you as a secretary, I am not sure.
The only thing you can do is walk over there and ask if there are any openings.
I do recommend becoming a certified nursing assistant. Even if you don't work at the rehab center, even a casual on call position in a nursing home will help with patient care skills when it's time for you to be graded for that stuff in clinicals.
Good luck!
