Hello. I just finished my second semester of an RN program. I have seen a few say your sciences need to be within 5 years, but how is that possible unless you apply to NA school within a year or two out of nursing school while being on a traditional path? I took my sciences between 2005-2007. I took Bio I and II, Chem I and II, Organic Chem I, A&P I and II, and Micro and have a 3.5 gpa in these classes. Was there any point in trying in these classes since they will be well beyond 5 years when I begin to apply to NA school? Also, do I need to retake the classes I made a B in, or retake them all since they will be over 5 years ago. Thanks a lot.
