Thanks for your reply. I'm feeling overwhelmed already! I haven't taken microbiology yet and plan to next summer. I just don't want to feel like I'm going in already behind. When I say my pre reqs were several years ago, I mean more than five. In fact, they're so old that if I applied to nursing school this instant, they would be outdated and I would have to redo them all. I'm a f/t teacher (so already very busy) and just wanted to refresh my memory on anything that's really helpful to know. Maybe get a jump on things. I ordered an a & p book to review, but it would help if I knew where to direct my studying.
