Greetings,

I've just passed the PMP exam on my first try. I'm posting a few study tips:
1 - Enroll in a PMP course. Ask around, or check your local PMP chapter, for a credible training provider
2 - Make sure you have the right prep material. I used McGraw-Hill Education PMP Project Management Professional Exam and I'm very happy with my choice. I also used the PMBOK as a reference.
3 - Prepare a study plan - It definitely helped me to organize my time and prioritize study time.

Best of luck
