IF you're have a choice of becoming CRNA or AA, What would you choose? And why? (Please answer insightful if you can) because i'm having trouble choosing between the two. I'm about to graduate with a chemistry degree and I don't want to waste two more years with another year of working as a RN to applying to NA program. But as a NA, you have much more flexibility with the job, such as: getting hired, working independent, and the area that you're going to live in later. ANY ADVICE.
