Preparing myself for ABSN while keeping my options open

[greenbean14]

I'm currently halfway through college as a biology major. I'm really not sure what I want to do with my bio degree, so I'm taking a career explorations class right now. Nursing really appeals to me, but I don't have any experience shadowing or knowing that it's what I definitely want to do, so I'm not sure if it would be good to switch to a Pre-Nursing major without knowing for sure. In fact, I think I'm going to enroll in a CNA program over the summer in my area so that I can get certified and gain experience in a nursing setting while being able to make some money during the rest of my undergrad. Hopefully, that can help steer me in the right direction as to whether or not an accelerated nursing program would be in my future.

That being said, I would really like to keep my options open. I came in with a lot of college credits, so my last 4 semesters have a lot of flexibility/open space as far as adding electives goes. Because of this, I'm starting to think that it would be a good idea to abandon my idea of obtaining a minor to use the extra space in my remaining semesters to do any remaining prerequisite coursework for accelerated nursing school. Courses like anatomy and physiology interest me a lot anyhow, and I'll feel a lot better knowing that I will keep my options to ABSN open, should that be the path I ultimately choose.

The only problem is that I'm not exactly sure where I want to end up after I graduate, and thus, I'm unsure as to where I would be attending an accelerated program as well. This poses a problem because it seems like different schools have slightly different prereqs. Can anyone help me out to generalize which prereqs I should enroll in?

Thank you so much to anyone who can offer any advice!
