"The actual questions on the real exam are not like what’s in this simulator because it let you answer many straight-forward and ITTO questions, but the exam asks you situational based questions only. " - are you sure you had ONLY situational questions on the exam?
Other people report a mix of 1) ITTO 2) situational and 3) formulas - I am beginning to think the PMP is a little bit of a gamble - depends how lucky you are in getting the type of questions you are strong in - when they randomly pick based on that weighted distribution( I 13%....P 24%....etc)...well thats life

Good luck people!
