I followed the program, created a study plan and planned to take the exam after 12 weeks. Used the video lessons while following along in the PMBOK first. I purchased two books, PM Master Prep book and Head First PMP. The two books helped me attain a level of deeper understanding and actually accelerated my learning curve.
** Please note: I took the test in 2017 after a bootcamp and reading Rita's book, I failed. I too the test again in 2018, read Rita's booka gain, read the PMBOK again, added an audiobook, and online practice tests, again. I failed, again.
PM PrepCasts guides, study plan, video series, practice tests, exam simulator(!!!!), and the additional books did it for me.
The big one to know, for me:
what does each process have in its ITTOs, what comes before and after that process (the flows), and the differences between the processes. Every question I needed to determine where I was in the processes and know the difference in what ITTO that I could use! If you misidentified the process, you automatically had the wrong answer!
4 out 5 above target, by the way!
You have to follow the plan provided, follow the videos, you should incorporate other materials for perspective, do the practice tests (40-100 questions a day) every day for a month at least, know the ITTOs for the knowledge area and the flows between them - and the exam is yours!
Also, I love the ability to test at home. The distraction at the testing centers, the people, and 1/4 mile walk to the bathroom always messed with my head.
