i'm currently a student vocational nurse and plan on doing the lvn to rn program at my community college. My campus does not require chemistry for lvn, just CNA, pharmacology, and a body survey course (anatomy and phisiology took care of that). I would talk to someone and check the prereqs yourself. as for chemistry, i would just work at it, i know i had a hard time with it. Check your campus offers tutoring, cause i know it helped me even though i got a low B. Good luck with your career path.
