I know how you feel. Unsure about being a RN. I was unsure, but decided I don't think it's for me. My advice to you is.. I would say if you are going into the dental field maybe you should look into a career as a Dental Hygienist, they make pretty good money and the hours are good of course. I think a 3 month Dental Assistant program is great! Most are 8 months long. Congrats and good luck! But if you definitely want to go into nursing I would take a CNA, Medical Assistant or LPN Course, it will help you as you transition into a RN. I'm a CNA now myself. My class was 8 weeks. I'm looking into X Ray Technologist or Occupational Therapist Assistant.
