Hi Sumanth,
Best of luck with your upcoming exam.
I found the real questions to be easier than the simulator questions, although I was under more time pressure during the real exam. During simulation exams I had more than enough time to review all my marked questions, while I did not have that luxury during the live exam - yet I passed much better than my passes during the simulations, so that is why I perceived the real exam questions to be easier.
Just a little tip - I was also 45 minutes early, and was then allowed to start the exam immediately, so eventually was finished 45 minutes earlier than I thought I would be. Not sure if all locations do that, but I found that a great benefit, as on exam day I just wanted to do the exam and not necessarily sit and brood on things before starting.
Regards, and ope to see PMP next to your name in 52 hours time...
