Biology Major

Hello all!
I am currently a college student, looking forward to graduate in winter with a bio degree.
My goal to be a nurse has not changed since the beginning of my college experience.
Meanwhile, I have finished all the pre-req courses that would meet with my school for nursing.
I have some silly questions to ask about how to get in to the school to build my career as a MALE nurse. Now, I am a bit frustrated over not starting to research earlier, and feels like I am in a position where there is not much time to apply for next fall programs.

How long will it take for me to be an RN?
Do you have to be an RN to go to school for masters degree? or is there a joint program for this case?

I have tons of questions to ask but I figured I should start asking above questions to start off my nursing career! If someone can inform me with an overall process to become a RN, It will help me a lot to take the first step!
Thanks a lot !
