Your opinions on PMP practice exam systems

I'm creating a PMP practice exam system. I think its different to what's out there at the moment for a couple of reasons:

1. It will increase your chances of passing by telling you which specific areas of knowledge you need to work more on.

2. It will predict when you should be able to take the test and pass it.

I would LOVE to hear your opinions of practice exam systems. So if you could take a short survey I would be very grateful (and you'll get chance to sign up for the FREE beta trial).

Here's a link to the survey -



 Don't have time to fill out the survey, but wanted to share my opinion that I personally don't think they are the most useful thing.  Personally, I'm fine just doing practice questions on paper.  But YMV and it certainly does help you get used to the computer interface.  :)
