I had attempted all of the questions in the simulator prior to the addition of the Beta questions. Upon several and now frequent attempts, I have attained a minimum passing score of 85% in those set of questions. I've however struggled with the beta set of questions. I've got only 16 days of access left on the simulator. I've had a 10 days break and planning to take the next 10 days to finalize my PMP study. I'm not sure I have enough time to cover the beta questions. Do I focus on the beta questions or the previous ones. I'm getting apprehensive with the beta questions.
