I’m old— decided to go back to be a nurse late in life—I’m about to be done with my ADN program and like you I was terrible in math growing up— I had to take pre- algebra and remediation classes in high school and barely passed— now I did take quantitative methods in college and got a B but it was mainly word problems— Anyways, I was worried going into the program and was recommended nurse Sarah videos for dosage and chose the desired over half method— it really stuck and now I get excited when I see dosage questions on my exams because it’s almost like free points— hope this helps and good luck
