I am a UK nurse and failed 1st time. Trying to figure out best way to tackle this big mountain. I have now obtained, Saunders, and LaCharity, Kaplan books. Do not know if best plod on myself, or look at Hurst, or NCSBN. Can someone tell me re NSCBN course, cost, and time involved etc? Any suggestions. I trained 20yrs ago, so things are not fresh in my mind.
