Hello, PMP warriors!
I had a very challenging preparation when I prepared my PMP. English was not my home language, but I chose to do my PMP in English.
I watched video prep cast and as well as all PMP video on You tube. I watch every subject, every process group, every word. You need to know every word or terms that Project Management is using and learn what is the difference. And I did the 4hrs exam simulator once during working hours and another 4hrs exam simulator every weekend. And during a week, I look at the wrong answer and I studied, why it's wrong.
The formulas, I hang it on my wall, and everyday, I learn it, to memorize it.
I prepared my PMP only for 2months as I did not have time. But with a perseverance, you can do it.
Good luck!
