Anyone CHPQ certified?

I got my CPHQ in the summer of 2007 and I thought it was the most difficult test I had ever taken in my life. I googled every topic listed on the content outline in the candidate's handbook and read an AHIMA book, "Quality and Performance Improvement in Healthcare: A Programmed Text". I remember there being a lot of clinical vignettes, little case scenarios you had to provide a solution to. It seems to be based on day-to-day practice, which is a good thing.
