First, that is to this group. I would have been fumbling around trying to study for this thing without you!
What I did:
I studied on and off for about 6 months. Honestly, you could probably do what i did in 1 if you are feeling super motivated.
I did AR PMP mindset questions FIRST. it helped me understand the mindset because honestly, that's what the test is testing you for.
Next I did PMP study hall basics - all questions, all tests. Lastly I did PMP study hall advanced, all tests.
Scores: my general score for the tests and quizzes where between 65 - 75%. Near the end of my studying, I was scoring around 72% pretty consistently. A huge thing that really helped was to review the tests AFTERWARDS. I would do a test, then the next day spend an hour going through the questions I got wrong. I would cover the answers and essentially do the wrong questions again.
Having been in academics, I can't recommend this strategy enough. Giving you mind a chance to refresh and revisiting the wrong questions is a stupidly powerful way to commit things to long term memory.
