. I'm new to N-Clex and I'm after some advise please:1) which is the best company to do it through? I'm in Uk.2) which are the best study guides3) is it expensive as I don't want to use a agency company as I have no desire to go out to US at present. It's something for future. Anyways if anyone can shed some light on what's best? I hear that Saunders is a good book? Thanks againFrom a Virgin N-clexer!!!
