Hello Lawrence,
Welcome. It is - in fact - very unusual that students stop by here and introduce themselves. We've only had a couple of handful of posts like this one. It's a shame, actually, because it puts a much more human face on the students for us and the questions they ask.
Hmmm... "the world's largest company" piqued my interest, so I "stalked" you on LinkedIn and was surprised to see that particular name. I had one or two other companies in mind, but that particular company was not on my list...
As far as your plan goes to sit for the PMP exam in 7-10 days, there may one solid roadblock to that: If you have not yet submitted your application to PMI then you may have to delay that plan. The PM PrepCast final exam and certificate of completion is only available to our students 14 days after the initial purchase. And PMI will not accept your application unless you have completed the course. But... if you have 35 hours of PM training from other sources, then you are good to go with submitting the application and don't need the PrepCast certificate because any PM training counts.
Lastly... out of curiosity... what was the other course that you had to return?
PS. One of my middle names is Martin. (not kidding).
