You are welcome. It is a pleasure.
I would say there is no straightforward answer regarding the ideal score before taking the real test. You could be having 90% correct answers with the best simulator and fail. First ensure you are using a recommended simulator like the one of Cornelius. Secondly, you are taking new questions. Thirdly it is recognised that if you have consistently (3 tines) 80% correct answers for new questions you have good chance to pass.
If you have read the PMP handout, you should know what to do on the day before and the exam day and all the precautions you should follow. For the study, no long reading at the time is not recommended. More practice is advised. Review and fix your areas of weaknesses and take more mock questions and run at least 4 full exams during the last week.
Believe in your self and your capacity to succeed. Do not overwhelm with a lot of tools. Tools offer by Cornelius are enough.
Good luck
