Congratulations Andrew! Earning the certification is a huge accomplishment especially as more and more jobs specifically ask for it for Project Manager positions.
I really like your suggestion about being positive and remaining dedicated to the process! It takes work but it is definitely worth it in the end. I would also add that all test takers should practice creating a brain dump a couple of days before your exam and time yourself so you can master it - it helps tremendously especially when your mind starts to get tired!
Congrats again and welcome to the PMP club!
P.S - for future test takers: I agree in principle with the message above that you do not need to get 100% of the answers right - just don't let your guard down! Remember that everything worth achieving requires hard work otherwise it wouldn't be valuable. I personally did mark the longer questions to come back to later. You'll have more than enough time to do so! Don't take any question lightly
