Ok, I'm thinking of going back to school (I'm 40, 41 in May) to take up nursing. Because I need to work, I decided to go LPN 1st, then in to RN program. I'm terrible at math but I have to take chemistry for health science course. How is this different than general chemistry? Is there a lot of math in Chem for health science? Should I brush up on my algebra skills? Thanks!
