Is any bachelors okay to be a CRO or do I need to study something in specific?
Any bachelors degree is fine, just make sure you are working on your leadership and physical fitness as well.
How did you get your bachelors degree in 16 months, is it like a special program or something?
I went through the Interservice Physician Assistant program. You earn a BS degree after the first 16 months (Phase 1), then you earn a Masters Degree in Physician Assistant Studies in the following 12 months (Phase 2).
