Additional Free Revision Questions adjusted to latest PMBOK version
Hey there are another few free PMP question bank and simulators that I have tried to use on my own, including an iphone app (so that I can carry on revision when I am away from the computer). These may be useful for anyone attempting your PMP exams. Some of the useful (and free!) resources are:
http://www.trial-exams.com (they are offering free access to all exam volumes now)
http://sites.google.com/site/pgmpguide/ (web-based exam questions database but without a simulator)
http://itunes.apple.com/sg/app/ace-exams/id381041217?mt=8 (iPhone PMP Exam simulation app)
PMZilla already has a great list of questions, and I think this will just be the icing on the cake.
Hope this helps and all the best!
