I passed the exam on 1-20-18. There are a few things that I would recommend for those looking to take the exam before it changes in March.
Focus on how processes, inputs, and outputs interact with each other and not on just memorizing them
Develop a deep understanding of how to apply the tools and techniques
Formulas are important, but understanding what the end numbers mean is critical
Use the PM Exam Simulator that OSP International offers, it will really help you understand how questions are asked
If you get lost or are having a hard time understanding certain concepts, just look them up on youtube and you will be able to find examples from other trainers
