Hello! I'm a pre-nursing student and I am not a science or maths person. Of course this didn't stop me when I entered an ER about two years ago and realized that this was my calling. So, I was just wondering, how much chemistry and math do nurses use on a daily basis? Is it ok to carry a calculator on the job? I did take chemistry and bio in school, (even though I retook chem in grade 12 because my grade was a 50..) So, should I take a few classes in like Pharmaceuticals before I apply for Nursing School?
