In the CPMA it says there are 24 audit cases in the Abstraction section, which lead to 52 questions. But then later on the page it says test takers will have to audit 20 cases? Are the 20 separate from the 24? Is it right to assume the 24 Abstraction cases are just text for you to read then the questions revolve around what you've read? And in addition there will be 20 cases you will have to audit on audit sheets - because it says you can bring any audit tool you want. All the audit tools I've seen are for E/M - is that true or are there also just plain audit tools somewhere online that I can look at?
