Yes, that is fine we need it to simulate the 'real' exam. But not being able to pause it and resume later doesn't help us prep for the 'real' exam. We need the questions to be 'real', not the time. The PMI exam prep test is the same, you can't pause it. With working and family, we just don't have dedicated time to sit for 3hrs to take a 'test' exam. We need to know if we are ready for the test by having a passing grade, not if we have time to site for 2-3hrs. That just isn't a relevant metric for test preparation, but passing the test is.
If you setup an option for 'timed' test and 'un-timed' test (to be able to pause and resume), I would purchase the CAPM prep series from PM PrepCast. Then I know that during what time I have available I can go through the test and resume the test when I have time. Yes, I'm aware of the quiz feature, but I need to practice the full exam test too.
I hope this feature can be added, I would be a customer today if it was.
