Rakshita,
I have two clarifications to what Joe has said:
2. What is the cost?
>> The cost for The PM PrepCast Elite (training and simulator) is $299
4. Once we complete the course, do you help set the exam?
>> Our company does not provide any assistance to you in regards to setting up the exam. You must fill in your exam application on your own and once approved you have to schedule it on your own. PMI has a good article about how the application process works here
