I am really excited, and can't wait to attend the Exam.
Thanks for the quick reply.
So, for now, I only need to know that CPI = EV / AC, regardless of how it is explained in term of ratio, becuase I got a little confused about how it was described in terms of ratio between page 2 and 8.
Based on our information and feedback from our students who have taken the exam, the Burn Rate has not come up as part of PMP Exam question. Therefore we did not include it in our formula guide. No need to make you learn something that isn't required.
As soon as students inform us that they encountered a new formula on the exam, then we will include it.
