I live in a rural area in northern Michigan, therefore I thought getting my EMT-b would make me more qualified, Then just a CNA. I never see job listings for E.R. Techs in my area. Mostly just nursing assistants in E.R. I love working to help people, animals in need, I like fast pace . To answer your question about letting Chemistry keep me from doing something. I believe it is very much harder for a hand-on person to be book smart and there is a difference . I am not book Smart I have test anxiety Plus a learning disability in math . I had to take basic college algebra twice in order to pass with 3.5. I took a half semester of Chemistry and drop it, just because I was total loss. So I don't believe that just wanting something bad enough can help you get it.
