You shouldn't give up. You can do this. Get the book called Dosage Calculations and study the metric system. You must know it by heart. My nursing school did not offer a class for dosage calc. It was a self study. First semster you had to get a 75 to pass the math, 2nd was 80, 3rd was 85 and the 4th 90%. I was registered for AP2 this semester. I dropped it because I was having second thoughts about myself being able to make it as a nurse. Science and math are not my strong suits but I could make it through the science but struggle badly with math. How much math do you actually use in nursing. I really want to become a nurse but this whole math thing is really brothering me. My professor this semester explained everything in terms of numbers and math equations. I think that he thought that it was a chem class and not AP. My professor from AP1 never discussed math when he taught the material. Thanks Tracy in NY
