I Love Quizlet. Also one I found that I really like is LearningNurse.com Lots of self-quizes there on body systems and such. I tend to learn really well when doing interactive learning on my computer. Hope it works as well for you too!
You know, I really used to hate that word too. But once I learned how to spell it, its acually kinda fun. diarrhea. there are lots of other medical terms also that end in "rrhea" Just try to remember rrhea then put dia in front of it.
