info on clinical refresher courses

I graduated from nursing school in 2004 but unfortunately never passed the nclex exam. I took the exam twice but due to unfortunate personal circumstances I got off track and never pursued a third attempt. I am now very eager to retake the exam but not sure where to start since i havent worked in the hospital for three years. Idealy i would like to take some kind of clinical refresher course but I'm not sure what is available since I'm not enrolled in any specific nursing program. I live in the northern virginia, DC area. Any information regarding any local courses or even just a point in the right direction would be more than helpful. thanks:wink2:
