TOPIC: About online PMP Exam

I am planning for sitting the PMP exam within this July 2020. Now I want to know about exam environment. I have some specific question listed below:
1. Has any opportunity to use paper, pen and calculator for brain dump and calculation?
2. As the duration of exam is 4 hours, have any opportunity to get any break within this? If yes then what are the condition? Have any opportunity to review the exam question at last or their is any division?
3. What are the computer/ laptop system requirement for sitting the exam from home.

thanks a lot.

1. Has any opportunity to use paper, pen and calculator for brain dump and calculation?
No, you are constrained to using the Whiteboard Application embedded in the exam software. It's essentially Microsoft Paint.
2. As the duration of exam is 4 hours, have any opportunity to get any break within this? If yes then what are the condition? Have any opportunity to review the exam question at last or their is any division?
You get the option for a 10 minute break after 90 questions. At this point you will review the first 90 questions as you cannot go back to change them after the break. The break time itself does not count towards your exam time.
3. What are the computer/ laptop system requirement for sitting the exam from home.
You'll have to check Pearson Vue's website and run the system test. If taking the exam on a PC you'll need Windows 10.
