This a site i found for quizzes on nursing.I have been doing them and found them helpful

I find that being in a seperate room to everyone else and a sign on the door that states" class in progress" works wonders for me. I also do extra time on the Mon and Wed after class as its still fresh in my head and always do half a hour to a hour after tea.
