Hi! I started pre-requisites at 53, got my CNA for experience and was glad as later a CNA was mandatory. I entered 2 year ADN program at 56 and took NCLEX at 58..passed at 75 questions! Been working ever since..am now 73 years old...in surgery and PACU. Love it!! Keep going and do not let anyone tell you you are too old. I have had a few apologies from surgeons who did tell me I was too old while doing clinicals. Fooled 'em all.
