...You worked hard in Nursing school, but you will work even harder through Pod school. Having a nursing degree is more advantage esp in 3rd and 4th year...
This is good advice^. If you went to Barry's nursing program or another pretty demanding BSN program, you know how to work, but even then, pod school is much more demanding. You have some tough basic science and the MCAT yet to go before applying, so use your time to learn more about podiatry and shadow some docs.
We have one RN and one NP in my Barry 09 class, and they're both very good students at or near the top of the class. I was a CNA in undergrad, I know we have one or two former EMTs, and some of my other classmates probably had various levels of health care experience before pod school also. It's surely an advantage to be comfortable dealing with patients and knowing hospital system structure - especially in the clinical years as was mentioned.
As for admissions stats, they are in flux every year at every pod program (just like M:F ratio, cultural diversity, etc etc). You could call admissions department, but stats only tell you about past classes. Every year and application cycle is different in terms of matriculant stats, student attrition, board pass, etc.
Just out of curiousity, why are you considering a career change when you haven't even worked as a RN yet? I have many successful friends in nursing and think it's a great career in terms of flexibility of hours, pay per hour, ability to switch specialties, etc.
