To earn your Project Management Professional (PMP)® credential, you need to meet the experience and education requirements, and pass the PMP® examination, a 200-question, multiple-choice test.

Regardless of how advanced your project management experience or education might be, you should still prepare vigorously for the exam.
Successful PMP candidates typically use multiple study aids, including courses, self-study and study groups.

On average, successful PMP candidates will spend 35 hours or more to prepare, so make sure you leave yourself plenty of preparation time before you take the exam.
