You have most of your core classes, you'll need Bio 101 and 102 and Microbiology.
It's not that hard but the A&P portion will require a lot of study. I found the class fascinating and was glad I took it.My instructor had a reputation of being tough, she was and I'm a better person for it.
I was accepted in to the nursing program but decided against it so I never did the clinical part, got a Phys.Ed. degree instead.
There is no shortage of nursing jobs but there is a shortage of teachers, that's why it's kind of cut throat to get in to the program.

That's my experience.
