Hi, I agree with Amy. It's best for you to feel comfortable with where you are - going in. It's hard to say / agree with how prepared you feel, it's really how you feel. I can tell you that I scored 76%, 68%, 74%, 71%, 77%, and 68%. I felt comfortable and confident and I did pass on my first try. If you feel like you know the 49 processes and all the formulas, and you are comfortable with both of these, then brush up on your focus areas the day before and be as prepared as you can / feel. I hope this helps.
