I also recently passed my PMP exam on the first try. I was surprised, as I didn't feel completely ready but needed to get in done as a step in the process. I was even more focused on Plan B (my contingency plan if I didn't pass) than my Plan A (what happens next after passing).
My suggestions:
* Read the PMBOK. It's boring as hell, but you've simply got to have that info.
* Download apps/games for PMP exam prep. Free ones: ITTO game, just to practice ITTOs for each process. Flash cards, practice test questions, etc. You'll be surprised at how often you will just grab your phone and spend 10-15 minutes on this stuff.
* PMPrepCast is really good prep material. Cornelius has a great delivery style and good tips. I went through it fully during the summer, then listened to the podcast version to review and prep over the past month. I had several study setbacks, so it was good to keep the same study materials over the course of months. And yes, I tried a variety of others as well, including a full Udemy course, but this one is it.
* Get your application done in a timely manner. I did not do this and stressed about it for months! Once it was done, submitted, and accepted, I really kicked myself in the rear for procrastination.
* Be prepared for the exam - don't stress or spend useless time with that Brain Dump. Seriously. You DO NOT get to do it during the tutorial, and once you see that timer going, the tension mounts up. I started it, then decided to must move on with my test and come back to it once I got my groove going. But I was prepared enough that I didn't need that crutch after all. Know your processes! Know your knowledge areas! Know your domains! Know your formulas!
* It seemed like I answered 50 questions over Risk Management! I'm sure it wasn't that many, but I'm pretty sure that the field test questions were all on that one knowledge area due to the frequency of Risk Management popping up on the test. At one point I thought that maybe this was just a Risk Management test and I was being punked. That kind of anxiety is unnecessary, but what do you do? Damn. At least it wasn't EVM! Small aspects of gratitude...
* I took my test in Lisbon, Portugal. I checked the site the day before to get my feel around the place. The test proctors working there had their coats on (December 6), so I asked if it would be cold like this in the center tomorrow. They seemed surprised that I thought it was cold, yet we were all standing in a modern office in a modern building wrapped in coats and scarves. And yes, it was hideously cold in the test room the next day. I wore a large sweater but left my coat in the locker, realizing several minutes into the test what a mistake that was. I needed gloves, leg warmers, woolly socks, a ski mask, etc. Seriously - a small space heater under the cubicle desk would provide SO MUCH comfort and remove distraction. During my restroom break, I was so thankful for the hand dryer so I could just thaw out my fingers!
If you are getting ready for the test, have faith in yourself, be diligent in your studies, and do your best. I hope to see you around the PM world soon!
