I am still in shock that I passed my PMP exam. You have an amazing program. My biggest tip is to follow everything that Cornelius says. I read the PMBOK twice, the Agile Practice Guide three times, and the Scrum guide twice. I also read The PMP Exam, How to Pass on Your First Try by Andy Crowe.
Did tons of practice questions and took all the exams except for the ITTOs. Did poorly on most exams but they are much harder than the real one. Watched the PrepCast and Booster Course videos. Read the lessons learned on the forum and watched the lessons learned YouTube videos. All of this hard work got me AT/AT/AT scores.
Lastly, I'd also recommend taking the exam at a test center. There were tech issues on Pearson's end for two of the online exams I scheduled. Took it at an exam center the last time and it went much more smoothly.
Again, thanks to PrepCast and to all aspiring PMs, don't give up and best wishes.
