After the Exam
Once you've completed your certification you'll also have to continue your education by obtaining at least 60 Professional Development Units (PDUs) over a three-year span. A PDU equates to one hour and you can earn these by attending PMI events, completing training through PMI Registered Education Providers, or by volunteering at PMI events.
The PMP certification requirements, like those carnival rides, aren't meant to make you furious. They exist to protect the value of your certification and add worth to a title that's not easy to achieve.
