Your questions have been answered here many, many times. I suggest you browse the forums a bit, and also check out the information on EC's website. Their ADN program page is here: Excelsior College | Program Details
Also, I highly recommend you download the School of Nursing catalog and read the entire section on the ADN program -- it tells you everything you need to know. The catalog is linked from that page.
Also, be aware that EC is not accepted for initial licensure or licensure at all in some states. Info is here: State Board Requirements - excelsior.edu
Good luck on your LPN boards!
