I hear you! I scored a 68 on Diagnostic and 68 on Readiness (so exactly what did I pay $400 for?!), and on Qbank and QTrainers I'm in the upper 50's to lower 60's. I don't think the strategy works...
I just graduated from a two year ADN program and its hard to get an OB job as a new grad, no matter what degree, around here. Most hospitals I've looked at want the OB nurses to have some experience....
