Thanks @PMP Aspirant. Answers below in red.
1) Did you encounter any questions that required calculation using formula such as CPI, SPI, Critical Path Method, EVM, EMV etc.? A few but never once used the calculator. You just have to recognize the situation the PM is in. For instance, if you have an SPI over 1 and a CPI under 1 what should you do?
2) Did you encounter any questions related to decision tree analysis, 5 why analysis etc.? Again, just know the concept as it might show up in a list of potential tools/techniques to apply to the scenario.
3) How many questions were there related to Hybrid methodology? The vast majority were agile. If you know agile and predictive environments well you will do fine.
