I have seen PMP Exam Simulation Contest! on PMPtrend with 200 online questions and if you win,The Contest winner will be given access to download once the PMPTrend PMP Exam Simulator v1.0.
 

Think PMZILLA members can use this and  win the contest. If not win atleast the 100 questions which they are providing for the context should be a tough one i guess.

I have not taken it yet and will take it up once i complete my first round of study.
