It's is a myth that 35 PDU’s are mandatory to take the PMP® Exam.
The actual fact is, you need 35 contact hours not the PDU’s to be able to apply for this exam. You can acquire this with the help of PMP Training.
You don’t have any use of PDU’s unless and until you bag the PMP® Certification. You need to earn 60 PDUs every three years to keep your PMP® Credential active.
