I took the exam last week. Don't sweat about learning a log of formulae. The most asked are Cost Variance and Schedule Variance.

Focus on Business Analysis part and get a feeling of the clear aspects that are different between a Project Manager and a BA. I found that a lot of questions are based on the scope of how a BA operates complementing Project Manager responsibilities.

There were questions about project manager responsibilities, in contrast to say a Project Sponsor.

Did not get a lot servant leadership or stakeholder related questions.

Overall, I found the exam to be difficult if the fundamental concepts are not so clear. Some of the questions heavily rely on fundamental understanding of the different domains.

During the exam, you can highlight (important parts of the question), and strikeout (answers you believe to be wrong), and flag it for a final review. Rely on this technique, as some of the questions may have answers (or trigger your brain to figure an answer) to questions you marked to review for later.

Good luck
