Abhirup, with simulator scores like that I think you should definitely pass. The only person who can spoil this for you now is YOU!
My advice is that during the exam do not lose focus. Be focused on answering the question in front of you and do not try to do simultaneous analysis of how you are doing overall in the exam. It can only help you panic.
Leave the job of computing your performance to the computer
Also, keep an eye on the clock. In my experience I had more spare time when working on the simulator but no spare time on the actual exam itself.
Good luck and look forward to a YAHOO! from your end soon
