While I agree it would be wise to keep your job so you can pay your bills, I have to disagree with the previous posters regarding experience in clinicals.
Of course, depending upon your program! I was in an ADN program at a local Technical college. I am so glad that I worked as a CNA, then Nurse Tech for experience. I found most clincials to be (dare I say it!) a waste of time and effort. The instructor had 8 students to look out for; as a student, we could not do "skills" or pass meds without an RN present-RNs on the floor were busy and said "Get your instructor", who by the way, was busy with someone else at the time!
My practical experience at work made all the difference in my comfort level for clinicals. When I graduated I felt comfortable because of that experience.
I have a friend who had no medical experience-she took a job as nurse tech and was she glad she did. I really helped to boost her confidence, as well as time managment and clinical skills.
Whatever you decide to do-good luck
