I took the Kaplan course and I scored very well, but I did not pass. It could have been anxiety that caused the mental block. I went to a tutor that was highly recommended. I did not think I would like her because she was abrupt and to the point. I passed with the min. Questions. She told me it wasn't that I didn't know the info, it was that I had little confidence in my knowledge so I over thought everything. Try not to be hard on yourself. Being a working LPN you have the knowledge, but your self confidence has taken a kick. Don't give up. Test in a different facility, and find a program or tutor that is different than what you have already done.
