Question about OU MSN

I am a new RN having received my ADN from TCC in May of 08. I have a non-nursing bachelors and I am going to take the OU Research course in the fall in preparation for entering the MSN program. I can try to test out of two undergraduate courses for Community based nursing and Leadership. The Community based nursing test is a NLN test. The Leadership test is a pass fail essay. Has anyone taken these exams? If so can you private message me or reply with ideas for success? For example, if you took either exam, what books did you use to study? How were the tests?

Thank you all in advance!
