Dear Frnds,

In one post i was reading that one pmp was consistant on 60% and has passed the exam, while his 2-3 friends were getting around 65 has been failed.

See here in tables 5 imaginary cases studied, how it can happened.

Below statistic shows how luck matters in PMP.

How  25 dummy questions may deflect your result you can see in below table in Case A versus Case B. 

A passer may fail , a failure may pass.
