I have been out of nursing for 20 years and need to take a refresher course. I am a little scared at the thought. Is there any advice out there and how difficult are these courses? I practiced for only a couple of years, (one med.surge and one in surgery), before I got married and stopped. Please let me know there is hope for me with this class. There will be six weeks in a classroom and then about 200 hours clinical. Any help would be wonderful. Thanks
