I am grateful to OSP international LLC for such an opportunity.
I passed the PMP exams on the 13th using the prepcast and the simulator.
I used other materials as well; but I found the prepcast quite useful because I could replay any topic several times till I understood it.
However, the exam simulator was for me the most useful.
The explainations for why each option was either right or wrong is quite helpful.
That was how I viewed every question in the exam and it paid off for me(what was the question actually asking and what it wasnt asking).
I am a happy man
