Sometimes the best nurses are the ones who have to repeat, is what my mentor told me. When u repeat it allows more to sink in that may not have the first time. I failed my very last med-surg class by 3 questions on a 200 question final. I was required to audit all previous classes before retaking that one. It was so hard to retake all those tests and listen to all those lectures again but I did and it was well worth it. I graduated, passed boards on my first try without any problems and I now enjoy the career I had always dreamed of. Nursing has to be in your heart and if it is then dont waste any more time. Go back, graduate, pass boards and start your career. Good luck
