I think you'd remember enough for nursing school, if you made A's. You can always get a A&P book at a Half-Price books, or Ebay, etc and review, if needed.
I'd look into if anyone still has a 10-year rule.
I understand what others are saying here, but at the same time, it is added costs to retake them.
I don't think you would be hurting yourself. I did retake A&P 1, but I remembered sooooo much, and it was over 10 years!
Best of luck to you!
