I chose the nursing school I will be attending in the fall mostly because of prereqs. There are just so many and this school had the least. When I applied, I was just so sick of taking classes that I just wanted to get into any school as soon as possible. This school is also one of the top 5 in the U.S and a lot of their students seem pretty happy. I didn't pay much attention to the cost which I kinda regret, but it'll be great experience nevertheless. I know I'll gain the experience I need to be a great nurse. Things that I think really helped me get in was my experience volunteering abroad, my prereq grades, and involvement and various activities (teaching assistant, college sport, coaching). I know this school looked at the whole package so GPA is not everything.
I think the greatest challenge will be time management and trying to study all the material thrown at us in a small period of time. For me, I know I have the ability to learn, but I'm just afraid I won't be able to do it all in a short allotted time. Especially since this material will be so dense. But everyone is faced with this challenge and we all learn to manage somehow.
Good luck! Don't let anyone scare you out of anything without trying it yourself.
