Question on where to go...stl area

So I wasn't sure of myself to start off in the medical field, so I made a decision (now I see probably a wrong one) to go to school for Medical Assisting. I will be done in March, do an externship then graduate. I want to be a nurse though, always wanted to.

I've checked out different colleges, associates vs. bachelors, price vs. price, everything! I just can't figure out exactly what to do. Meremac has such a long waiting list and I just don't know. I mean, I'll still have to take pre-reqs and all, like Bio and Chem even before I can apply for the program..is it worth it? I mean, I would be able to work as a rma while I take these classes and all, but it seems like the end is it not in sight. any suggestions?

Thank you!!
