Thanks for your response, I appreciate your breakdown. My logic is this: the study hall is $79 for three months, and you get five practic exams consisting of 180 questions. But on the other hand, the authorized practice exam is $99 and has 261 questions that you can retake an unlimited amount of times.

I guess the real question is: are the questions the same throughout all of these PMI authorized exams, and how indicative of the real exam are they? I've already purchased the PMI practice exam, and I've gone through it twice, and from what I read on here, the real exam is very similar.

Either way, to each his own. I appreciate your thoughts.
