Hello Jhon Fredery
First of all, thanks for your interest in using The PM PrepCast to earn your 60 PDUs. (And just to confirm, this course not only covers the 60 PDUs you need, but it also covers the 8/8/8 minimum you need in the three talent triangle areas.)
Don't worry too much about the Final Exam. It is really quite easy. Since you are already PMP certified, you can probably take the Final Exam 'in your sleep'. It is a 25 question exam and you have to answer 17 questions correctly to receive the certificate. If you don't pass at first, then you can take it again, and again, and again, until you pass. There is no time limit during the exam either.
Overall, we see that more than 85% of our students pass it on their first attempt. I'm sure you'll be part of this group.
Until Next Time,
Cornelius Fichtner, PMP, CSM
