Anamtha:
You will get "immediate feedback" in general terms from the testing center. For example, Initiating, Planning, Executing, Monitoring and Controlling, and Closing. These will be scored Above Target, Target, Below Target and Needs Improvement. Note carefully what those mean: Effectively, Above Target and Target mean Pass, Below Target and Needs Improvement mean Fail. A few days later you will be able to log on to your account at PMI (pmi.org --> Mi PMI-->Dashboard-->Exam Analysis) to look specifically at the exam areas. The analysis WILL NOT tell you which questions you missed, only what sections of the PMI Handbook you tested strongly and weakly in.
The simulator scores will tell you how you did in each area (Initiating, Planning, Executing...). However with the simulator you can go back and look at the questions and answers.
Good luck.
