I think it will be important for you to carve out some time out of work to do a couple of full-exam simulators so that you can get the actual feel for the exam.
Also, you can take as many breaks as you want to during the exam, however those breaks count against your exam time. If you can maintain focus, I might recommend a 5-10 minute break at 100 questions and then another short one at about 175 questions. That worked especially well for me.
I am preparing for the PMP, currently in last stages of preparation, the challenge I am facing now is its hard to maintain focus for the entire duration of exam, currently, I am doing 50 questions exam each time,
I can not spend 4 hours on the exam during office hours. need opinions.
