Hello Everyone

I'm looking at getting my PMP at some point.

I fulfill the requirements: ie: Bachelors and Maters degree, I also have the required 35 hours of training.  I would need 4500 hours of experience and this is where my question comes in.

I worked as part of the PMO for a large company for 3 years so I have the months/hours covered in terms of the experience needed but I am not 100% sure of the actual work I did within the project.
