Lpn

Hi,
I graduated w my ADN in May, took the NCLEX but did not pass. I am preparing to take the test again in Feb. Until I pass the NCLEX I have to work as a "patient care tech"...which I don't care much to do.
I've decided, though, that if I do not pass the test this second time, I want to try to take the LPN exam. Hopefully working as an LPN will give me a better understanding of some of the nursing material. Does anyone know the process involved to apply for the LPN test? Do I need to have a special LPN certificate if I already graduated nursing school?
Thanks.
